摘要： A system of driving stability control, which is adapted to control valves for opening and closing hydraulic pressure passages between a master cylinder and brake units of wheels and simultaneously controls pressurizing valves and a pressure relief valves so as to supply braking force selectively and independently to the brake units when a specified driving condition is detected, performs the coordinated braking control that, when a specified step-on pressure is detected during execution of the driving stability control, delivers the braking pressure to the brake units according to brake pedal travels as the driving intends simultaneously with reducing the participative degree of the driving stability control so as to ensure gripping force of wheels that brake the vehicle and reduces reduce the participative degree of the driving stability control with an intention of regarding driving stability of the vehicle as important when the vehicle is going to cause a spin.

摘要： An automotive vehicle stability control system determined which is a main cause of a change in a change rate of a yaw rate difference of an actual yaw rate from a target yaw rate between a change in the actual yaw rate and a change in the target yaw rate when the change rate of the yaw rate difference exceeds a specified change rate, increase threshold slip angle for starting braking control based on slip angle following the driver's intention when the main cause is the change in the actual yaw rate and increases an upper limit of target slip angle so as to allow the target slip angle to be increased according to a driver's steering operation when the slip angle preferential braking control takes place.

摘要： When the difference between the number of revolutions of each tire of a vehicle is judged by the tire air pressure warning device must be made under the condition that the number of revolutions of the four wheels must constantly be detected by different units, and processed at a high speed, and where the vehicle is travelling in a straight line, and at a point in time when all four wheels become at the same condition. In the case that all four wheels do not reach the same condition, the judgment of the difference in the number of tire revolutions at the tire air pressure warning device is prohibited. Also, using the vehicle running conditions, the most suitable tire air pressure judgment is carried out, and various noise generate when the vehicle is travelling do not have any effect, and the tire air pressure abnormality is detected with good accuracy, the detected signal from the wheel velocity sensors is carefully selected, and the reliability and accuracy of the tire air pressure judgment is improved. When the vehicle and/or the road surface is in a specific condition, by prohibiting the tire air pressure judgment, the reliability and accuracy of the tire air pressure judgment is increased. By permitting the tire air pressure judgment when within a vehicle velocity region, that is established using the road conditions, the reliability and accuracy of the tire air pressure judgment is improved.
