摘要： In a vehicle control device capable of sufficiently exhibiting the effect of vehicle control, a selection section selects a value greater than an intermediate value of a vehicle weight in a range restricted by a range restriction unit as the value of the vehicle weight and selects a value greater than an intermediate value of the height of the center of gravity in the range as the value of the height of the center of gravity. For stability, the greater the height of the center of gravity of the vehicle is, the stricter the conditions that are imposed. For fuel consumption, the greater the vehicle weight is, the stricter the conditions that are imposed. The selection section selects the values which become conditions stricter than at least an intermediate value in the range restricted by the range restriction section, and the range restriction section restricts the range.

摘要： A brake control system and method controls a braking operation in a vehicle. When a pressure sensor and a stroke sensor are functioning normally, a brake control system calculates a final target deceleration Gt as a weighted sum of a target deceleration Gpt that is based on a master cylinder pressure Pm and a target deceleration Gst that is based on a depression stroke St, and a braking force is controlled based on the final target deceleration Gt. On the other hand, when there is an abnormality in the stroke sensor, the brake control system calculates a target deceleration Gpt that is greater than when the stroke sensor is functioning normally in a region where the braking amount is small, and the target deceleration Gpt is set to the final target deceleration Gt. When there is an abnormality in the pressure sensor, the brake control system calculates a target deceleration Gst that is larger than when the pressure sensor is functioning normally in a range where the braking amount is large, and the target deceleration Gst is set to the final target deceleration Gt.

摘要： A vehicle control device capable of obtaining the sufficient effect of vehicle control is provided. A vehicle control device 1 outputs a control signal to a vehicle on the basis of the height of the center of gravity based on the behavior of the vehicle at the time of rolling or pitching or the correlation value correlated with the height of the center of gravity, and the control signal is calculated on the basis of acceleration of the vehicle in which a rolling angle or a pitch angle is reflected. The operation device calculates the height of the center of gravity or the vehicle weight on the basis of acceleration of the vehicle in which the rolling angle or the pitch angle is reflected and calculates a control signal on the basis of the height of the center of gravity or the vehicle weight. Thus, since the vehicle control device 1 can calculate the control signal on the basis of the acceleration of the vehicle in which the rolling angle or the pitch angle is reflected, it is possible to perform accurate vehicle control according to the rolling angle or the pitch angle at the time of rolling or pitching of the vehicle.

摘要： Disclosed is a specification information estimating device which estimates the steering gear ratio n of a vehicle. A specification information estimating device includes a steering angle sensor 26 and a yaw rate sensor 51 which acquire the wheel steering angle St and the yaw rate Yr of the vehicle during traveling, and an ECU 4 which estimates a steering gear ratio n on the basis of the wheel steering angle St and the yaw rate Yr acquired by the steering angle sensor 26 and the yaw rate sensor 51. Therefore, it is possible to estimate the steering gear ratio n of each vehicle without using a stability factor KH.
