摘要： A wheel state obtaining system configured to obtain a wheel state that is a state of at least one of a plurality of wheels of a vehicle includes: a wheel speed detection device configured to detect a wheel speed of each of the plurality of wheels; a traveling state detection device configured to detect a traveling state of the vehicle; and a controller. When the traveling state of the vehicle detected by the traveling state detection device is a predetermined set state, the controller obtains a wheel speed difference of two of the plurality of wheels based on the wheel speeds of the plurality of wheels detected by the wheel speed detection device. The controller determines whether at least one of the two wheels is in an abnormal state based on the wheel speed difference.

摘要： A control device includes one or more processors that is configured to: receive a plurality of first requests from a driver assistance system; arbitrate the plurality of first requests; calculate a second request, which has a physical quantity different from the first request, based on an arbitration result; and distribute the second request to at least one of a plurality of actuator systems. When a difference between the second request based on a previous arbitration result and the second request based on a current arbitration result is larger than a threshold value, the one or more processors are configured to distribute a request that is a value between the second request based on the previous arbitration result and the second request based on the current arbitration result.

摘要： A vehicle braking force control apparatus of the disclosure executes a slip rate reduction control to reduce a slip rate of any of wheels of a vehicle becoming equal to or greater than a predetermined slip rate threshold by automatically changing braking force applied to one or more of the wheels. The apparatus uses a first slip rate threshold as the predetermined slip rate threshold during a normal acceleration-and-deceleration control and a normal steering control. The apparatus uses a second slip rate threshold during a driving assist control. The second slip rate is set to a value smaller than the first slip rate threshold and near and smaller than the slip rate, at which a friction coefficient between the wheel and a surface of a road on which the vehicle moves is maximum.
