Certainly, in other examples, such as when the braking distance of brake pedal 150 increases, cause being formed between the piston 131a of the master cylinder 131 of itself and hydraulic brake system 130 mechanical decoupled state when removing, control unit 110 mechanically directly feeds back to the thrust of brake pedal 150 in response to the brake torque required by driver and hydraulic brake system and produces the drive singal of linear electromagnetic actuator 140.In these examples, except according to except the brake torque required by driver, also the braking mode according to vehicle is determined the drive singal of linear electromagnetic actuator 140.
As shown in Figure 3, as favourable mode, between the movable part 140a and described first connecting rod 153 of aforesaid rectilinear electromagnetic driver 140, be provided with a pushing part 160, the other end of aforementioned first connecting rod 153 is configured to be connected with the movable part 140a of linear electromagnetic actuator 140 by this pushing part 160.
Link with the movable part 140a of linear electromagnetic actuator 140 in aforementioned pushing part 160, the thrust that the movable part 140a of linear electromagnetic actuator 140 produces is passed on first connecting rod 153 by this pushing part 160, thus is applied to further on brake pedal 150.
Shown in composition graphs 3, in example of the present disclosure, when brake pedal 150 is depressed, being formed mechanically decoupled between the piston 131a of the master cylinder 131 of brake pedal 150 and hydraulic brake system 130, being formed mechanically decoupled between the piston 131a realizing the master cylinder 131 of brake pedal 150 and hydraulic brake system 130 in this example by leaving a space between described pushing part 160 and the driven part 133 of aforesaid supercharging actuator 132.
As favourable mode, aforesaid pushing part 160 is preferably configured to horizontal " convex " shape structure, there is a body 160a for being fixedly connected with the movable part 140a of linear electromagnetic actuator 140, such as by realizations such as bolts, and a salient 160b, be configured to the shape protruding aforementioned body 160a, and protrude towards the direction of the piston 131a of the master cylinder 131 of described hydraulic brake system 130.In this example, the path between the piston 131a of this salient 160b and master cylinder 131 leaves space mechanically decoupled with what formed between the piston 131a of the master cylinder 131 of hydraulic brake system 130 and brake pedal 150.
So, when brake pedal 150 is depressed, shown in composition graphs 3, due to the existence in the space of aforementioned setting, hydraulic brake system 130 (the piston 131a of master cylinder) is incited somebody to action not action immediately and produces hydraulic braking force, thus the whole braking procedure of the intervention preventing hydraulic braking too early or excessive.Now, the pedal travel electric signal that nationality is produced by the aforementioned such as angular transducer and/or pedal stroke sensor mentioned, the required brake torque of control unit 110 computing driver also divides configuration brake torque based on the regenerative braking torque preferentially meeting regeneration brake system 120, ideally wish brake torque be all reproduced brake system 120 utilize to realize the maximum recovery of energy, if the available brake torque of regeneration brake system 120 is enough, the lock torque that then vehicle is provided by motor slows down, storage battery is charged simultaneously, realize regenerative brake.
But, if beyond regeneration braking capacity, (ceiling capacity that namely regeneration brake system is current reclaims ability to the deceleration demand of driver (namely required brake torque), the current available torque peak of motor, the charge rate of storage battery, the driving power etc. of electrical equipment actuator is depended on) as aforementioned, then need to provide hydraulic braking moment of torsion accordingly and complete car brakeing by the coordination of hydraulic brake system 130, meeting the deceleration demand of driver.Now, aforementioned required brake torque and the difference of regenerative braking torque of distributing by as hydraulic braking torque distribution to hydraulic brake system 130, produce braking force to make car brakeing by the piston movement of its master cylinder 131, the thrust that especially also can such as be provided by supercharging actuator 132 is promoted.
While pedal brake occurs (namely when producing braking requirement), due to the effect of regeneration brake system, if do not provide the feedback that pedal brake is felt, then likely there are erroneous judgement or other negative consequences, therefore produced by the movable part 140a of linear electromagnetic actuator 140 in the present example and hinder the resistance of pedal advance and be applied on brake pedal 150, to eliminate this unfavorable sensation.
