A vehicle control system for an autonomous vehicle includes: a first control device configured to generate a first driving plan including desired lateral lane driving positions or desired lateral lane driving position ranges; a plurality of first sensors configured to obtain information on motion of the vehicle and information on surroundings of the vehicle; and a second control device configured to communicate with the first control device, generate, based on the first driving plan obtained from the first control device and the information obtained by the first sensors, a second driving plan different from the first driving plan, the second driving plan including target lateral lane driving positions or target lateral lane driving position ranges, and control driving operation of the vehicle based on the second driving plan.

Vehicle control system and vehicle control device for autonomous vehicle

A vehicle travel control device executes vehicle travel control such that a vehicle follows a target trajectory. An automated driving control device generates a first target trajectory that is the target trajectory for automated driving of the vehicle. The vehicle travel control device further determines whether or not an activation condition of travel assist control is satisfied. When the activation condition is satisfied, the vehicle travel control device generates a second target trajectory that is the target trajectory for the travel assist control. Even when the second target trajectory is generated during the automated driving, or when the second target trajectory is generated during the automated driving and a priority condition for giving priority to the first target trajectory is satisfied, the vehicle travel control device executes the vehicle travel control by giving more weight to the first target trajectory than to the second target trajectory.

Vehicle control system

A vehicle control system generates at least one primary candidate of a target trajectory for an automated driving of a vehicle and executes a primary evaluation. An evaluation index of the primary evaluation includes a travel safety level of a travel to follow the primary candidate. The primary candidate having highest travel safety level is selected as at least one strong candidate of the target trajectory. If only one is selected as the strong candidate, the vehicle control system determines the selected strong candidate as a finalist candidate of the target trajectory. If two or more strong candidates are selected, the vehicle control system executes a secondary evaluation for the strong candidates to determine the finalist candidate. An additional evaluation index is used in the secondary evaluation.

A multilayer piezoelectric element using an alkaline niobate-based piezoelectric ceramic, which can inhibit its reliability from dropping while lowering production cost, is characterized by forming internal electrodes () with a metal whose silver content is 80 percent by mass or higher, and also constituting piezoelectric ceramic layers () with a piezoelectric ceramic whose primary component is an alkaline niobate having a perovskite structure and which also contains a lithium manganate.

A system for controlling a trailer brake output circuit includes an electronic control unit having one or more processors and one or more memory modules. The trailer brake output circuit is configured to output a trailer brake output signal. Machine readable instructions cause the electronic control unit to: receive a signal from a vehicle stability control system indicating that a vehicle stability control flag is set, generate the trailer brake output signal in response to the vehicle stability control flag being set such that the trailer brake output signal ramps up to a target value over a predefined period of time, maintain the trailer brake output signal at the target value while the vehicle stability control flag is set, and output the trailer brake output signal such that the trailer brake output signal ramps down from the target value when the vehicle stability control flag changes from set to not set.

Systems, vehicles, and methods for vehicle stability control and trailer brake control collaboration

A multilayer piezoelectric ceramic is such that: its piezoelectric ceramic layers do not contain lead as a constituent element, and have a perovskite compound expressed by the composition formula LiNaKNbO(where 0.02<x≤0.1, 0.02<x+y≤1), as the primary component; and the internal electrode layers are constituted by a metal containing silver by 80 percent by mass or more, and contain ceramic grains containing the same elements found in the primary component. The multilayer piezoelectric element has a long lifespan, and whose internal electrode layers have a high content percentage of silver.

A vehicle control system generates a first target trajectory, which is a target trajectory for an automated driving of a vehicle, and executes vehicle travel control based on the first target trajectory. The vehicle control system generates a second target trajectory which is a target trajectory which does not conflict with a restrict condition, when the travel based on the first target trajectory conflicts with a safety restrict condition, and executes travel assist control by using the second target trajectory. The vehicle control system judges whether or not a resurgence condition is satisfied by using the first target trajectory that is generated during the execution of the travel assist control. If it is judged that the resurgence condition is satisfied, the vehicle control system returns to the execution of the vehicle travel control from that of the travel assist control.

A driving device generates a driving signal and outputs the driving signal to a piezoelectric element, the driving signal having a waveform obtained by using, as a first modulated wave, a first low-frequency wave having a frequency of 1 Hz or more and less than 100 Hz, using, as a second modulated wave, a waveform obtained by modulating an amplitude of a second low-frequency wave having a frequency of 100 Hz or more and 300 Hz or less with the first modulated wave, and modulating a high-frequency wave having a frequency of 20 kHz or more and 100 kHz or less with the second modulated wave.

A vehicle traveling control system according to the example in the present disclosure communicates with an automatic operation control system which drafts a traveling plan of the vehicle, and performs an automatic traveling control for automatically running the vehicle along the traveling plan received from the automatic operation control system. The vehicle traveling control system predicts a risk based on information about surrounding environment of the vehicle, and performs, when the risk is predicted, a risk avoidance control to intervene in the automatic traveling control in order to avoid the risk. When the risk avoidance control is executed, the vehicle traveling control system transmits information on the risk avoidance control to the automatic operation control system.

A vehicle control system includes a first unit configured to generate a target trajectory based on a travel plan of the vehicle, and a second unit configured to execute vehicle travel control such that the vehicle follows the target trajectory. During the automated driving, the first unit transmits automated driving information to the second unit. The system includes a memory device in which driving environment information is stored, and a processor for controlling a travel control amount. During the automated driving, the processor executes preventive safety control for intervening in the travel control amount so as to prevent or avoid a collision between the vehicle and an obstacle based on the driving environment information. In the preventive safety control, the processor changes an intervention degree to the travel control amount based on the automated driving information.

A vehicle travel control device executes vehicle travel control such that a vehicle follows a target trajectory. An automated driving control device generates a first target trajectory that is the target trajectory for automated driving of the vehicle. The vehicle travel control device further determines whether or not an activation condition of travel assist control is satisfied. When the activation condition is satisfied, the vehicle travel control device generates a second target trajectory that is the target trajectory for the travel assist control. When the second target trajectory is generated during the automated driving, or when the second target trajectory is generated during the automated driving and a priority condition for giving priority to the second target trajectory is satisfied, the vehicle travel control device executes the vehicle travel control by giving more weight to the second target trajectory than to the first target trajectory.
