The vehicle control system of the present disclosure includes a meter-side control device that is installed in a vehicle and can measure the total distance traveled by the vehicle, and a backup device that can obtain a copy of the total distance measured by the meter-side control device. Data communication between the meter-side control device and the backup device uses an authentication signal using a common key, and a new communication between the meter-side control device and the backup device When registering a common key, the larger value of the total mileage value stored in the meter side control device and the total mileage value stored in the backup device is sent to the meter side control device. Total mileage.

Vehicle control system

A driving assistance device includes a visibility determination unit that determines whether visual recognition within a predetermined distance from a vehicle can be achieved in a traveling direction of the vehicle, an operation detection unit that detects an operation of causing the vehicle to enter a space in which an oncoming vehicle travels, based on information representing an operation of the vehicle by a driver, and a control warning unit that warns the driver or controls the vehicle in such a way that the vehicle does not enter the space when the visibility determination unit determines that visual recognition within the predetermined distance cannot be achieved, and the operation detection unit detects the operation of causing the vehicle to enter the space.

Driving assistance device

A vehicle includes an engine, an MG (motor generator) an MG, a planetary gear device mechanically coupled to the engine and MGand MG, a battery, an inverter configured to perform a power conversion between the battery and MGand between the battery and MG, and a controller. MGgenerates a counter-electromotive torque when rotated by the engine. During an inverter-less running control where the inverter is put into a gate shut-off state and the engine is driven to cause MGto generate the counter-electromotive torque, the controller decreases a engine target rotation speed Netag when an integrated value of battery charging current (deterioration evaluation value D) is greater than a predetermined value (threshold value D) smaller than the engine target rotation speed Netag when the deterioration evaluation value D is equal to or smaller than the threshold value D

Hybrid vehicle

When there is an abnormality in communications between a motor ECU and an HVECU in an automobile, the motor ECU controls a motor such that creep torque or a given torque larger than the creep torque is delivered from the motor. Thus, when there is an abnormality in communications between the HVECU and the motor ECU, the automobile is able to run in a limp home mode.

Automobile including motor for running the automobile

A PM-ECU configured to control a drive torque of a vehicle is configured to be stopped in response to a driver's operation of a start switch and then activated in response to a driver's re-operation of the start switch. The PM-ECU is configured to be activated and place a restriction on the drive torque of the vehicle, in response to a re-operation of the start switch after the PM-ECU is stopped in response to an operation of the start switch. The PM-ECU is configured to remove the restriction on the drive torque in response to a reduction of an operation amount by which an accelerator pedal is operated.

Control system of vehicle

In a control device for a hybrid vehicle, the charge/discharge setting unit sets a charge/discharge demand for an electricity storage device during a limp home mode, and the operation control unit controls an engine and a motor generator such that the electricity storage device receives/outputs a power in accordance with the charge/discharge demand set by the charge/discharge setting unit. In the case where a charge/discharge amount X input/output to/from the electricity storage device when the engine is operated to generate a required driving force is smaller than a charge/discharge amount Y based on the charged state of the electricity storage device, the charge/discharge setting unit sets, as the charge/discharge demand, the smaller one of the charge/discharge amount Y and a charge/discharge amount Z based on the upper-limit rotation speed of the engine set in accordance with a torque transmitted by a drive shaft.

Control device for hybrid vehicle, hybrid vehicle provided with same, and control method for hybrid vehicle

A control system for a vehicle capable of changing a deceleration by changing a shift range, includes: a PM-ECU for controlling a powertrain of the vehicle; and a start switch operated by a driver to start and stop the PM-ECU. When the start switch is operated during travel of the vehicle, the PM-ECU stops control of the powertrain. When the PM-ECU stops control of the powertrain and thereafter the start switch is operated again during travel of the vehicle, the PM-ECU controls the shift range in accordance with an elapsed time since the PM-ECU stopped control of the powertrain.

Control system for vehicle

A vehicle includes an accelerator pedal, a drive device and an electronic control unit (ECU). The drive device generates driving force for driving a wheel on the basis of an operation amount of the accelerator pedal. The ECU, while the vehicle is travelling in a ready-off state, prohibits a shift into a ready-on state until the operation amount of the accelerator pedal once becomes lower than a predetermined value.
