A communication apparatus according to the present disclosure is a communication apparatus included in a first vehicle, the communication apparatus including a communication interface and a controller. The communication interface communicates with a server. The controller detects a second vehicle located in a vicinity of the first vehicle. The controller generates positional information for the second vehicle based on a position of the first vehicle when the second vehicle is detected. The controller transmits the positional information for the second vehicle to the server via the communication interface, when the communication interface can communicate with the server. The controller stores the positional information for the second vehicle as unsent information for the first vehicle, when the communication interface cannot communicate with the server, and transmits the unsent information for the first vehicle to the server via the communication interface, when the communication interface becomes able to communicate with the server.

A control system for a vehicle including a power transmission system and a switching device has an electronic control unit configured to make a door open-close determination as to whether a door of the vehicle is open or closed, using an open-close signal indicating opening or closing of the door, and execute automatic parking control by causing the switching device to switch the power transmission system to the parking state, when the door open-close determination indicates that the door is open, while the vehicle is stopped with the power transmission system placed in the non-parking state. The electronic control unit determines that the door is open, when the open-close signal generated from at least one of a plurality of sensors provided for the same door changes from a close signal to an open signal.

Control system for vehicle

A vehicle control apparatus includes: a brake control portion which is configured, when a vehicle is stopped, to cause a braking apparatus to keep a stopped state in which the vehicle is held stopped independently of operation of a brake pedal of the vehicle; a driver-assistance control portion which is configured to start a driver assistance operation in response to a manual operation made by the operator, and which is configured, when the stopped state is kept by the brake control portion, to withhold start of the driver assistance operation; and a withhold cancel portion which is configured, when a returning operation of the brake pedal has been made by the operator, to cause the driver-assistance control portion to cancel withhold of the start of the driver assistance operation.

Vehicle control apparatus

A control apparatus for a vehicle provided with drive wheels, an automatic transmission, and a manual shifting device for shifting the automatic transmission, the control apparatus includes an automatic parking control portion configured to implement an automatic parking control for automatically parking the vehicle in a predetermined parking space, and controls the automatic transmission to be shifted according to a shifting control signal corresponding to an operation of the manual shifting device, the automatic parking control portion comprising a shifting control portion configured to place the automatic transmission in a power-cutoff state in which a vehicle drive force is not transmitted to the drive wheels, when the manual shifting device is operated to a position a running direction in which is different from a running direction of the vehicle when the automatic parking control is implemented.

Control apparatus for vehicle

A vehicle shift control device comprises: a shift position deciding portion deciding a shift position of a shift operating device based on a sensor signal output according to an operation of the shift operating device; and a drive power output command portion selecting a shift range based on a shift position determination signal output from the shift position deciding portion to cause a vehicle to run, when a communication abnormality has occurred so that the shift position determination signal is not transmitted from the shift position deciding portion to the drive power output command portion, the vehicle shift control device selecting a shift range maintained at the time of occurrence of the communication abnormality of the shift position determination signal if a vehicle speed is equal to or greater than a predetermined value, and selecting a neutral range if the vehicle speed is less than the predetermined value.

Vehicle shift control device

An operator is a momentary operator. An electronic control unit is configured to when the operator does not pass through any one of traveling operation positions while the operator is operated from an initial position to an neutral operation position and then returned to the initial position, and when the operator is continuously held at the neutral operation position for a first predetermined time or longer, change a shift range of an automatic transmission to the neutral range, and when the operator passes through at least one of the traveling operation positions while the operator is operated from the initial position to the neutral operation position and then returned to the initial position, prohibit a change of the shift range to the neutral range even when the operator is continuously held at the neutral operation position for the first predetermined time or longer.

A shift range is selected based on a vehicle speed or acceleration of a vehicle and a shift range kept by a drive unit at the time when it is determined that there is a malfunction in shift sensors. Thus, it is possible to avoid a disabled self-propelled state resulting from a change into a neutral range through a fail-safe operation and keep limp home running.

Shift control system for vehicle and shift control method for vehicle

Vehicle speed limit apparatus

An upper-limit vehicle speed should be prevented from being set to speed different from an intention of a driver. When it is detected that a speed limit is changed, an upper-limit vehicle speed setting ECU temporarily switches a control mode from a normal mode to an inquiry mode. An ASL operation unit serves a function for a change operation of upper-limit vehicle speed in the normal mode, and serves a function for a reply operation about whether the speed limit is accepted in the inquiry mode. When the ASL operation unit is operated in the normal mode, the upper-limit vehicle speed setting ECU does not switch the control mode to the inquiry mode, even if a change of a speed limit is detected, until a certain period of time (a certain period during which a mode switching prohibition period is set) has passed since the operation.

Vehicle speed limiting device

A vehicle speed control apparatus generate a speed command value to control a vehicle speed according to a detected treading amount of an accelerator pedal, determines an upper-limit speed of the vehicle according to a speed limit of a road, generates a limit command value to control the vehicle speed to be the upper-limit speed, and adjusts the vehicle speed according to one of the speed command value and the limit command value to cause the lower vehicle speed. If the upper-limit speed is updated due to a change in the speed limit of the road while the vehicle speed is being adjusted according to the limit command value, a rate of change of the vehicle speed is limited continuously until a predetermined timing.

Vehicle speed control apparatus, and vehicle

A speed limit value that is set for a road where a vehicle is travelling is used to limit a driving force of the vehicle. If a new speed limit value is acquired, which differs from a currently used speed limit value, and the vehicle is in a state where the driving force is limited based on the currently used speed limit value, a switching screen page enabling an occupant of the vehicle to input a switching instruction to switch the speed limit value used to limit the driving force is displayed. Then, if the occupant inputs the switching instruction in response to the switching screen page being displayed, the speed limit value used to limit the driving force is switched to the new speed limit value.
