SYSTEM AND METHOD FOR CONTROLLING BRAKING DEVICES IN A HYBRID VEHCILE

摘要

Braking control system for a motor vehicle, of the kind comprising a front power plant (1) comprising at least one electric machine, connected to a front wheelset (3a, 3b), a rear power plant (2) comprising at least one electric machine, connected to a rear wheelset (4a, 4b), a friction braking device (5a, 5b, 6a, 6b) for each of the wheels of the vehicle and controlled by a control means (11), sensors (7), and an electronic control unit (ECU). The control system comprises a means (25) of apportioning the demand for braking, a means (24) of apportioning the regenerative braking and a means (26) of apportioning the demand for braking between the front and rear wheelsets, the control system being capable of apportioning the demand for braking between the friction braking devices and the electric machines of the power plants which are used as regenerative braking devices, and of determining a range of values for apportioning the regenerative braking between the front and rear wheelsets as a function of friction braking references.
