That's easy! You control the speed downward to stop the car. As a final year student you should figure this out yourself.

You need a controller that allows 4 quadrant operation and to brake just let the motor run as a generator and send the power back to charge the battery or at worst dump it in a resistor bank. This approach is used all the time in industry for braking of motor loads. The 4 quadrant power controller requires twice as many power components as the regular one but that's the way it is.
