Braking system of a hybrid vehicle with the front and rear regeneration braking with different activities

摘要

Braking system of a hybrid motor vehicle comprising a pair of front wheels and a pair of rear wheels, with:a front regeneration braking a direction which is selectively the front wheels with a regeneration of electrical energy from a kinetic energy of the vehicle with a first regeneration capacity of the effective braking;a rear regeneration braking a direction which is selectively the rear wheels with a regeneration of electrical energy from the kinetic energy of the vehicle with a second regeneration capacity of the effective braking;a front friction braking a direction (36fl, 36fr, 38fl, 38fr), which brakes the front wheels selectively;a rear friction braking a direction (36rl, 36rr, 38rl, 38rr), which brakes selectively the rear wheels; anda control device (24, 50), which the front and rear regeneration braking a direction and the front and rear friction braking a direction (36fl, 36fr, 38fl, 38fr, 36rl, 36rr, 38rl, 38rr),the front and rear regeneration braking a direction is designed such that the first regeneration capacity of the effective greater than the second regeneration is active; andthe control device (24, 50) the front and rear regeneration braking a direction and the front and rear friction braking a direction (36fl, 36fr, 38fl, 38fr, 36rl, 36rr, 38rl, 38rr) operates in such a way that, when the vehicle with a braking torque demanded by the driver (tbd) is braked, the front regeneration a regularity of the direction of such a high braking torque (tref), such as available and in this case within a predetermined maximum value (trefmax) permanently under the condition applies to the front wheels, that a ratio of a brake torque applied to the rear wheels (trer + tmr) to a braking torque applied to the front wheels (tref + tmf-system) is not greater than a predetermined value (α), which in turn to a value of less than one is determined, ..
