    摘要： In order to prevent deceleration (G) shock due to a braking torque on a driving wheel temporarily reaching zero during a coast down shift, this control system for an electric vehicle is provided with: an automatic transmission (3) that is positioned on a drive train from a motor generator (MG2) to a driving wheel (14), and carries out down shifting according to combination of the disengagement of a friction clutch (9c) and the engagement of an engagement clutch (8c); and a shift controller (21) that carries out shift control of the automatic transmission (3). An integrated controller (30), which carries out regenerative cooperative brake control through a substitution in which a friction torque is increased by a friction braking device (15) provided to the driving wheel (14) by tracking a reduction in a regenerative torque when a regenerative torque is reduced by the second motor generator (M2), is provided to a hybrid vehicle. The shift controller (21) matches the timing of the start of coast down shift control, which involves disengaging the friction clutch (9c), with the timing after at least a substitution involving regenerative cooperative braking control has started.

    摘要： A vehicle 100 (Figure 1) includes a braking system 100a (Figure 2) that includes a foundation braking system 111 and a hydraulic braking system 112. According to method 100b (Figures 3 and 4), system controller 117 (Figure 2) at successive steps 120-127 determines when hydraulic regenerative braking system 112 cannot provide full commanded braking torque and acts through proportional treadle valve 116a to provide a proportional transition between an isolated hydraulic braking mode and an isolated foundation braking mode. According to methods 200b (Figures 7-8) and 200b (Figures 9-10), proportional braking is approximated. According to method 300 (Figure 11), hydraulic braking is reduced at the initiation of a braking event based upon the estimated kinetic energy of the vehicle and available capacity for storing that energy.
