More new vehicles
are being equipped with Electronic Parking Brakes or EPB. The parking brake is
just one more system that has been integrated into the onboard electronics to
provide a smarter, safer and more convenient means of braking the wheels under
a variety of situations.
Advantages of the Electronic Parking Brake
electronic parking brake eliminates the bulky parking brake lever or pedal
inside the car. An electronic parking brake only needs a small switch or button
that can be located anywhere and activated by fingertip. It requires no effort,
and no thought in the case of a smart EPB system. The smart EPB system
automatically applies the brake without driver input when the vehicle stops
moving or the transmission is placed in Park.
electronic parking brake can also have a built-in intelligent release function
so that it is not accidentally left on when the transmission is placed in gear.
The EPB can also be used to provide a "hill holding" capability on
vehicles with manual transmissions so the car doesn't roll backwards, or
forwards, when stopped on a slope.
can also function as an emergency brake should the hydraulic brakes fail --
although when applying the rear brakes only, it can take a long time to slow
down or stop a speeding vehicle. Even so, it's better than no backup at all.
