A braking system for a motor vehicle having braking wheels 16, 18, a service brake pedal, a friction braking system operative upon the braking wheels 16, 18 in response to actuation of the vehicle brake pedal 26, an anti-lock braking system cooperative with the friction braking system to control the friction braking force applied to the braking wheels 16, 18 upon detection of slippage of the braking wheels 16, 18, a regenerative braking system operative upon the braking wheels 16, 18 in response to actuation of the vehicle brake pedal 26 for selectively generating an applied regenerative braking force through the braking wheels 16, 18, and an ambient temperature sensor 52. The regenerative braking system operates at a first effective rate of applied regenerative braking force upon application of the brake pedal 26 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.
