Kraftfahrzeug-Antriebssteuerungssystem.

摘要

A system (1) for automatically controlling a motor vehicle drive unit (8), which system comprises a hydraulic actuating unit (16) for actuating a control member (17) controlling selection and engagement of the gears on the vehicle transmission (7); a hydraulic actuator (24) for actuating a control member (25) controlling the clutch (5); and an electronic control system (9) for processing input signals relative to operating parameters of the drive unit (8) and vehicle in general, and for controlling the actuators (16, 24) to varying degrees of automation. In particular, the control system (9) produces variable control signals for respective proportional solenoid valves (18, 27) controlling the actuators (16, 24), so as to vary hydraulic supply to the actuators (16, 24) and consequently the actuating force of the same, for simulating operation by a skilled driver; the aforementioned control system (9) also providing, when shifting gear, for controlling the speed of the engine (2) so as to minimise slippage of the clutch (5).
