A control device controls a vehicle including a seat suspension which is provided between a chassis and a seat of the vehicle and restricts vibration and of which each of a spring constant and a damping coefficient is changeable and controllable. The control device detects, as vehicle information, a vehicle speed, an acceleration, a state of acceleration operation by a driver, a state of deceleration operation by the driver, and a state of steering by the driver. The control device determines, based on the vehicle information, whether the driver has driving preference of emphasizing the steering stability performance of the vehicle or driving preference of emphasizing the ride comfort performance of the vehicle, and, according to the determined driving preference, changes an acceleration of the seat by controlling the seat suspension.

Vehicle control device

A control system is intended for a vehicle having an automatic stop-restart function that automatically stops an engine when a predetermined automatic stop condition is satisfied and restarts the engine when a predetermined restart condition is satisfied during an automatic engine stop. The control system has an automatic stop restricting function that, when the host vehicle is located in a first predetermined area before a temporary stop sign, prohibits an automatic stop of the engine. When a preceding vehicle is located in the first predetermined area, the automatic stop restricting function is deactivated.

Control system for vehicle

A vehicle comprising an internal combustion engine, a preceding vehicle information acquiring device for acquiring preceding vehicle information relating to a preceding vehicle, including a parameter relating to a distance between vehicles which becomes greater the wider the distance between a host vehicle and the preceding vehicle, and an electronic control unit for controlling the internal combustion engine, in which, the electronic control unit is configured so that when the parameter becomes a first predetermined value or more during the idle reduction mode where the internal combustion engine is automatically made to stop, it makes the internal combustion engine automatically restart and so that if the host vehicle continues stopped even after making the internal combustion engine automatically restart, it again makes the internal combustion engine automatically stop when the preceding vehicle has stopped before the parameter becomes a second predetermined value larger than the first predetermined value.

Vehicle drive source control based on preceding vehicle

A vehicle comprising an internal combustion engine, a preceding vehicle information acquiring device for acquiring preceding vehicle information relating to a preceding vehicle, including a parameter relating to a distance between vehicles which becomes greater the wider the distance between a host vehicle and the preceding vehicle, and an electronic control unit for controlling the internal combustion engine, in which, the electronic control unit is configured to initiate an idle reduction mode where the internal combustion engine is made to automatically stop when a preset engine stop condition stands and to continue the idle reduction mode if the preceding vehicle is decelerating or has stopped and to make the internal combustion engine automatically restart if the preceding vehicle is accelerating or is running at an equal speed when the parameter becomes a first predetermined value or more during the idle reduction mode.
