Engine torque controlling device responsive to the acceleration of the vehicle and slippage of the wheels
First Claim
1. An engine torque controlling system for a vehicle, said system comprising:
- engine torque adjusting means for adjusting the engine torque independently of operation by a driver,first engine torque setting means for setting a first aimed engine torque in response to a magnitude of lateral acceleration applied to said vehicle during turning of said vehicle,second engine torque setting means for setting a second aimed engine torque in response to an amount of slip of a driving wheel of said vehicle,selector means for selecting and outputting said second aimed engine torque whenever said first aimed engine torque has been set by said first engine torque setting means and said second aimed engine torque has been set by said second engine torque setting means regardless of the values of said first and second aimed engine torques, andengine torque controlling means for controlling said engine torque adjusting means so that the torque of said engine becomes equal to the aimed torque engine torque selected by said selector means.

Abstract
A driving torque controlling system by which a vehicle can drive with safety and certainty while maintaining an appropriate posture without dissatisfying the will of a driver very much. The driving torque controlling system comprises a control signal selecting section which selects, in response to a predetermined change-over condition, one of control signals from a turning control unit for setting an aimed driving torque in response to a magnitude of lateral acceleration applied to the vehicle during turning of the vehicle and a slip control unit for setting an aimed driving torque in response to an amount of slip of a driving wheel of the vehicle. A torque controlling unit receives a selected control signal from the control signal selecting means and reduces the driving torque of the vehicle in response to the received control signal independently of operation by a driver of the vehicle.
