Abstract
A braking system for a motor vehicle having braking wheels,, a service brake pedal, a friction braking system operative upon the braking wheels,in response to actuation of the vehicle brake pedal,, an anti-lock braking system cooperative with the friction braking system to control the friction braking force applied to the braking wheels,upon detection of slippage of the braking wheels,, a regenerative braking system operative upon the braking wheels,in response to actuation of the vehicle brake pedal,for selectively generating an applied regenerative braking force through the braking wheels,, and an ambient temperature sensor,. The regenerative braking system operates at a first effective rate of applied regenerative braking force upon application of the brake pedal,at an ambient temperature above a desired temperature, and the regenerative braking system operates at a second, lower effective rate of applied regenerative braking force at an ambient temperature below a desired temperature. Upon activation of the anti-lock braking system, the applied regenerative braking force is reduced at a first predetermined rate when the ambient temperature is above a desired temperature and the regenerative braking force is reduced at a second, faster predetermined rate when the ambient temperature is below a desired temperature.
