摘要：
The device comprises an electronic control unit (10) that can detect a request from a driver to perform a single or multiple downshift. The control unit receives a first boolean signal (BR) associated with brake pedal (6) pressure and a second boolean signal (PAD) associated with pressure on a spring-back actuator (7), and the control unit delivers a third boolean signal requesting a single downshift (Mono_R) and a fourth boolean signal (Multi_R) requesting a multiple downshift. The electronic control unit (10) triggers a time delay when the actuator is activated and maintains same as long as the actuator is activated.
