Title:
A BRAKING SYSTEM FOR A VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/128192
Kind Code:
A3
Abstract:
A braking system (100) for a vehicle comprises: a regenerative braking system (110) and a friction braking system (120). The friction braking system (120) comprises one or more traditional friction brakes (121), which are operable to deccelerate the vehicle in a conventional manner and further comprises a cooling device (122) operable to cool the one or more friction brakes (121). The cooling device (122) comprises one or more blowers (123) and a means (124) for directing air produced by said blowers (123) towards the friction brakes (121). The regenerative braking system (110) comprises an electric motor (111) that is configurable to operate as an electric generator. The electric motor (111) is connected to one or more of the vehicle's road wheels and is operable to deccelerate the vehicle by using one or more of said wheels to drive electric motor (111) to generate electric energy. By doing this, the regenerative braking system (101) is operable to recover energy when braking the vehicle. The regenerative braking system (110) is operable to direct at least part of the recovered energy to the cooling device (122) and/or the battery (112). When the regenerative braking system (110) is utilised, it preferentially directs the recovered energy to battery (112). When the battery (112) is at substantially full capacity, the regenerative braking system (110) directs the recovered energy to the cooling device (122). When the friction braking system (120) is utilised, the cooling device (122) is actuated and directs air at the friction brakes (121).
