System and method for reducing vehicle bouncing
First Claim
1. A method for controlling vehicle bouncing of a vehicle having an engine driving wheels through a transmission having multiple gear ratios, and having a fuel control unit for supplying a variable amount of fuel to the engine in response to fuel control signals generated by an engine control unit, the method comprising:
- setting a control code as a function of a gear ratio of the transmission;
sensing vehicle acceleration with an accelerometer mounted on the vehicle and generating an acceleration signal in response to motion of the vehicle;
generating an output signal as a function of the control code and the acceleration signal; and
modifying fuel delivered to the engine as a function of the output signal.

Abstract
A system and method is described for controlling vehicle bouncing of a vehicle having an engine driving wheels through a transmission having multiple gear ratios. The vehicle has a fuel control unit for supplying a variable amount of fuel to the engine in response to fuel control signals generated by an engine control unit. The method includes generating a control code as a function of a gear ratio of the transmission; sensing vehicle acceleration with an accelerometer mounted on the vehicle and generating an acceleration signal in response to motion of the vehicle. The fuel control signal is generated as a function of the control code, the acceleration signal and a frequency dependent transfer function value. The fuel delivered to the engine is modified as a function of the fuel control signal.
