摘要： A brake control section can select an automatic mode in which a mechanical brake is automatically transitioned from a released state to a braking state in response to the running condition of a vehicle. A diagnostic section outputs a fail signal when an abnormal condition of the brake control section is detected. A power control section automatically stops a drive power source of the vehicle when the running condition of the vehicle satisfies a predetermined condition for determining a vehicle stop. When the automatic mode of the brake control section is released or when the diagnostic section outputs a fail signal of the brake control section, the power control section is inhibited to automatically stop the drive power source, so that an unintentional movement of the vehicle caused by an inclination of the road surface and the automatic stop of the drive power source can be prevented.

摘要： A correlation coefficient computing unit receives front-left and front-right wheel-accelerations from high-pass filters, each having a driver-operating component removed therefrom, and computes a correlation coefficient therebetween. A computing-unit of upper and lower limits of a correlation coefficient of a population sets upper and lower limits of a correlation coefficient of a population. First and second correction-gain setting units set first and second correction-gains varying in accordance with running and driving states, respectively. A correlation coefficient computing unit of a population computes a correlation coefficient of a population of this time based on the correlation coefficients computed as above, a correlation coefficient of a population of the previous time, the upper and lower limits, and the first and second correction-gains. A coefficient of friction on road surface estimating unit estimates a coefficient of friction on road surface by comparing the correlation coefficient of the population of this time with a determining threshold value previously set according to the running state.

摘要： A vehicle behavior control apparatus is divided into three major parts, sensors for detecting engine and vehicle operating conditions, a target yaw rate establishing section for establishing the rate and differential limiting apparatuses for selectively varying distribution ratios of driving force between front and rear wheels and/or between left and right wheels. The target yaw rate establishing section calculates a target yaw rate based on a vehicle mass, a mass distribution ratio between front and rear axles, front and rear axle mass, distances between front and rear axles and a center of gravity, a steering angle of a front wheel, and front and rear wheels equivalent cornering powers. A steady state yaw rate gain is separately calculated for left and right steering, respectively. A reference yaw rate is calculated by correcting a time constant of lag of yaw rate with respect to steering based on estimated road friction coefficient.

摘要： A control system for a brake vacuum pump, the system being capable of accumulating a negative pressure required for a vacuum chamber, without excessively operating the vacuum pump. In this system, an EGI_ECU determines whether a vehicle has experienced running at a speed equal to or higher than a preset creep vehicle speed after the startup of an engine. The EGI_ECU prohibits the operation of the vacuum pump until the time when the vehicle experiences running at a speed equal to or higher than the creep vehicle speed. Thereby, in a situation obviously not requiring a strong braking force, such as in a stopped state immediately after the startup of the engine, the operation of the vacuum pump can be prohibited, which allows the vacuum pump to be accurately prevented from an unnecessary drive.

摘要： A correction factor setting unit sets correction factors for a front-rear traction distribution control unit, an anti-lock brake control unit, a traction control unit, and a braking power control unit according to the situation of a road and the shape thereof which are inputted from a road information recognizing unit. At this time, the correction factors are preset values according to the situation of the road and the shape thereof so that the actions of the control units will be balanced with each other. Consequently, the plurality of vehicle behavior control units mounted in a vehicle act efficiently according to the situation of the road, on which the vehicle is driven forwards, and the shape thereof while quickly responding to the situation of the road and the shape thereof. Besides, the actions of the vehicle behavior control units are balanced with one another.
