In a vehicle contact avoidance assist system () for providing assistance in avoiding an obstacle located ahead of a vehicle including a contact avoidance control unit () configured to perform an obstacle avoidance operation upon detecting an obstacle located ahead of the vehicle, the obstacle avoidance operation including a steering of the steerable wheel via the steering actuator so as to avoid the obstacle, the contact avoidance control unit is configured to apply a restriction on the obstacle avoidance operation depending on a detected gripping state detected by a steering wheel gripping state detection unit ().

Vehicle contact avoidance assist system

A vehicle control apparatus is equipped with a vehicle velocity detecting unit that detects a vehicle velocity of a driver's own vehicle, and an automatic brake control unit configured to carry out an automatic brake control process for causing a braking force to be generated automatically in the wheels without reliance on a braking operation when the vehicle is involved in a collision. The automatic brake control unit makes the braking force to the wheels smaller as the vehicle velocity becomes higher after the vehicle collision.

Vehicle control apparatus

In a control system for an internal combustion engine having a plurality of cylinders and mounted on a vehicle, in which the engine operation is switched based on the throttle opening between a full-cylinder operation in which all of the cylinders are operative and a cut-off cylinder operation in which some of the cylinders are inoperative, and a running control including at least a cruise control in which the vehicle runs at a desired vehicle velocity is conducted, the engine operation is switched to the full-cylinder operation when it is determined that deceleration is required in the running control, so as to increase pumping loss (engine loss). With this, it becomes possible to generate the deceleration sufficiently as desired, when, for example, the vehicle descends a downhill.

Control system for cylinder cut-off internal combustion engine

The deterioration of receiving environment of a reflected signal from a preceding vehicle in an auto-cruise control is immediately detected, so that the distance between the vehicle and the preceding vehicle detected by a distance sensor comprising a laser radar, is maintained constant. On the basis of data of the magnitude of received signals, which are detected by the distance sensor and accumulated over a predetermined time, a standard deviation (or a dispersion) and an average value of the magnitude of the received signal are calculated. If the standard deviation is equal to or larger than a reference value or the average value is equal to or smaller than a reference value when the distance sensor has not detected a reflected signal, it is determined that the environment of reception of the reflected signal from the preceding vehicle has deteriorated, whereby the auto-cruise control is discontinued, or the deterioration of the receiving environment is informed to a driver by an informing device.
