Abstract: A vehicle motion control apparatus includes a control unit which controls a steering apparatus and a brake apparatus provided in a vehicle. The control unit acquires a normative motion state amount necessary for the vehicle to trace a target traveling path, acquires a target motion state amount necessary for generating a yaw moment to cancel unstable behavior of the vehicle, and acquires a target steering angle for generating a steering angle moment and a target brake force for generating a brake moment, to obtain a necessary yaw moment generated by the vehicle. The control unit outputs a first control command for obtaining the target steering angle to the steering apparatus and outputs a second control command for obtaining the target brake force to the brake apparatus.

Abstract: Achieved is a load drive device capable of suppressing local concentration of temperature at the time of absorbing a counter electromotive force of an inductive load while suppressing a size of a power transistor. The load drive device includes a first transistor connected between a first control electrode and an inductive load. Further, the load drive device includes an active clamp circuit that becomes conductive when a terminal voltage of a second control electrode between the first transistor and the inductive load exceeds a threshold. Furthermore, the load drive device includes a second transistor connected to the second control electrode and connected in parallel to the first transistor.
