SIMULATED THROTTLE KICKDOWN IN AUTOMATED MECHANICAL TRANSMISSION

摘要

Across the spectrum of automatic transmissions, rapidly depressing the accelerator pedal to floor is interpreted by the transmission and associated components as a request for increased engine power to, for example, pass another vehicle or climb a hill. A method of operating an automated mechanical transmission includes a throttle position sensor and electronic control unit and provides a simulated signal in response to various full throttle positions and travel. Various time and position dependent relationships such as substantially fully depressed throttle, rapidly depressed throttle, throttle maintained substantially fully depressed and throttle substantially fully released before being depressed, i.e., a "pumped" throttle are sensed by the throttle position sensor and interpreted as a throttle kickdown by the electronic control unit which generates a kickdown signal.
