Abstract: In a vehicle control apparatus employing a first speed self-adjustment control system configured to control a speed of a host vehicle based on a first command value, in a manner so as to maintain a distance of the host vehicle from a preceding vehicle or to maintain a set speed, a second speed self-adjustment control system is provided for controlling the host vehicle's speed based on a second command value determined based on information about a lateral acceleration acting on the host vehicle. Also provided is a deceleration selector configured to select either one of the first and second command values, which selected command value produces a greater deceleration exerted on the host vehicle. A control unit is configured to control the host vehicle's speed by driving an actuator based on the selected command value.

Abstract: There is provided a vehicle motion control system which carries out acceleration and deceleration of a vehicle which satisfies driving feeling of a driver even in the state where a lateral motion of the vehicle is not involved. The vehicle motion control system includes a curve shape acquisition section 2 for acquiring a curve shape ahead of an own vehicle, an own vehicle position acquisition section 3 for acquiring a position of the own vehicle, and a vehicle motion control calculation section 4 for calculating a command value of a longitudinal acceleration generated for the vehicle based on the curve shape and the position of the own vehicle. The vehicle motion control calculation section 4 calculates a plurality of negative longitudinal acceleration command values during travel of the own vehicle from before a curve to a point where a curve curvature becomes constant or maximum after the vehicle enters into the curve. The longitudinal acceleration command values are changed based on at least one of: an estimate of the maximum lateral acceleration which is presumably generated during traveling a curve ahead of the own vehicle; a grade of the road ahead of the own vehicle, pedal operation by the driver, and a turning direction.

Abstract: A vehicle control apparatus includes a first section that recognizes a lane boundary line of a lane in which a vehicle is traveling. A second section recognizes a present position of a predetermined reference point of the vehicle. A third section calculates a predicted position of the reference point, wherein the predicted position is a predetermined interval ahead of the present position. A fourth calculates an imaginary lane boundary line, wherein the imaginary lane boundary line is tangent to the lane boundary line at a point close to the predicted position. A fifth section performs a control of preventing the vehicle from deviating from the lane by controlling the vehicle depending on positional relationship between the vehicle and the lane boundary line. A sixth section selectively permits and suppresses the control depending on positional relationship among the imaginary lane boundary line, the present position, and the predicted position.

Abstract: A brake system provided with a brake booster using intake negative pressure of an engine for boosting a brake operating force for a vehicle. A requested braking force is detected base on an operating amount of a brake pedal, and when the requested braking force is less than a threshold value, a master cylinder pressure prevailing in the master cylinder using an operating force boosted by the brake booster is supplied to the wheel cylinder. On the other hand, when the requested braking force is greater than or equal to the threshold value, brake fluid pressure having been boosted by a pump is supplied to the wheel cylinder. The threshold value is set to a value that becomes greater the larger the negative pressure inside the brake booster.
