Driven wheel torque control system

A driven wheel output torque control system for use in a vehicle having a prime mover, comprising:

• a slip condition detecting means for detecting a slip condition of a driven wheel of a vehicle during acceleration condition of said vehicle;
• an operation quantity detecting means for detecting an operation quantity of an operating element for adjusting an output torque from the prime mover of the vehicle;
• a grip force detecting means for detecting a grip force of a road surface in accordance with an acceleration value of said vehicle and said slip condition;
• an output torque gain changing means for changing an output torque control gain from the prime mover with respect to an output from the operation quantity detecting means on the basis of an output from said grip force detecting means;
• and
• a gain variable output torque control means for adjusting an output torque from said prime mover on the basis of the output torque control gain changed by said output control gain changing means.

A driven wheel torque control system for use in a vehicle having a prime mover, comprising:

• a slip-reduction output torque control means for adjusting an output torque from the vehicle in accordance with a slipping state of a driven wheel driven by said prime mover in order to reduce an excessive slipping of the driven wheel;
• an operation quantity detecting means for detecting an operation quantity of an operating element for adjusting the output torque from said prime mover;
• a grip force detecting means for detecting a grip force of a road surface;
• an output torque gain changing means for changing an output torque control gain from the prime mover with respect to an output from the operation quantity detecting means on the basis of an output from the grip force detecting means;
• and
• a gain variable output torque control means for adjusting an output torque from said prime mover on the basis of the output torque control gain changed by said output control gain changing means.
