PURPOSE: A synthesized electronic control circuit of a vehicle wheel locking device and a drive force controller is provided to integrate each electronic controller, to control the prevention of vehicle wheel locking and drive force and to save production costs and an installation space. CONSTITUTION: In case that an ABS(anti-lock brake system) integrated element relay(13) is turned on according to a control signal outputted from a first microcontroller and an interface circuit(11), exciting coils(L1..Ln) of a solenoid valve are actuated. In case of the ABS integrated element relay is turned off, the exciting coils are not actuated. When a TCS(traction control system) integrated element relay(14) is turned on according to a control signal outputted from a second microcontroller and an interface circuit(12), a coil of a direct servo motor is actuated. When the relay(14) is turned off, the coil is not actuated. With a normal ABS integrated element relay and a normal vehicle wheel locking device, an ABS OK mark is brightly displayed by turning on an ABS verification lamp(2). With an electric defect in the ABS integrated element relay and the vehicle wheel locking device, the ABS OK mark is not displayed. With a normal TCS integrated element relay and a normal drive force controller, a TCS OK mark is brightly displayed by turning on a TCS verification lamp(4). With an electric defect, the TCS OK mark is not displayed by turning off the TCS verification lamp. Thus, the vehicle locking prevention and the drive force are controlled through the synthesized electronic controller.
