Abstract:
A control system for a vehicle having a fixed gear transmission and an engine that outputs an actual RPM signal is provided. The control system includes a vehicle bus, a shifting module, a simulated RPM module, and an engine sound enhancement (“ESE”) module. The vehicle bus transmits a signal indicating a plurality of operating conditions of the vehicle. The shifting module receives the signal from the vehicle bus to determine if the operating parameters of the vehicle indicate that a gear shift by the fixed gear transmission is imminent within a predetermined amount of time. The simulated RPM module is in communication with the shifting module for generating a simulated RPM signal if the gear shift is imminent. The simulated RPM signal has a greater increase in engine RPM with respect to time prior to the gear shift compared to the actual RPM signal.
