Hybrid vehicle with regenerative braking control |
摘要 |
A motor vehicle 11 has an engine 12 driving a transmission 13 which in turn drives a front final drive unit 14 connected to a pair of front wheels 15 by front driveshafts 16. The front final drive unit 14 also drives a rear drive take-off unit 17 which is connected to a rear final drive unit 18 by a longitudinal propshaft 19. The rear final drive unit 18 is connected to a pair of rear wheels 21 by rear driveshafts 22. The rear final drive unit 18 houses a traction motor/generator 35 which can drive the rear wheels 21 through an epicyclic reduction gear 39 a crownwheel 27 and pinion 31. The pinion 31 is also driven by the propshaft 19 through a control coupling 33. An integrated starter generator (ISG) 29, is driven by the engine 12. Both the traction motor/generator 35 and the ISG 29 draw current from or supply current to a traction battery 61. The traction motor/generator 35 can provide regenerative braking, the temperature of the traction motor/generator being monitored and the ISG 29 arranged to provide regenerative braking instead when the traction motor/generator reaches a prescribed temperature limit. The control of supplemented regenerative braking avoids undue reliance on other retarding means. |
