Provided is a vehicle control system that appropriately performs synchronization control for a plurality of control systems. A monitoring circuit generates a command signal when only a first reset signal is input. The monitoring circuit generates a command signal when the state in which only the first reset signal is input is changed to the state in which the input of the first reset signal is stopped. With the command signal, a second clock signal is output to a timer generator as a second timing signal. With the command signal, the second clock signal generated by a second synchronization signal generating circuit is output to a first synchronization signal generating circuit, and a third clock signal generated by the first synchronization signal generating circuit is output to a timer generator as a first timing signal.

Vehicle control system

A motor control device includes an anomaly detection means that detects an anomaly occurring on power feeding paths of respective phases on the basis of first electric current values, second electric current values of the respective phases and a phase electric current value obtained by the first electric current values and the second electric current values. When at least one of an absolute value of the first electric current value and an absolute value of the second electric current value exceeds a first threshold value corresponding to a limit value of an electric current detection and an absolute value of the phase electric current value is smaller than a second threshold value corresponding to zero in any one phase, the anomaly detection means determines that an anomaly of an electric current sensor has occurred as regards the corresponding phase.

Motor control device and electric power steering device

A control ON/OFF determination unit determines that oversteer control should be started in the case where a slip angle differential value is equal to or greater than a predetermined threshold value, the sign of the slip angle differential value is identical with the sign of a yaw rate, the sign of a steering wheel turning angle is identical with the sign of a steering wheel turning speed, and a vehicle speed is equal to or greater than a predetermined threshold value.
