System overview
If the Parking Support Brake deter-
mines that a collision with a detected
object is possible, the hybrid system
output will be restricted to restrain any
increase in the vehicle speed. (Hybrid
system output restriction control: See

Additionally, if the accelerator pedal
continues to be depressed, the brakes
will be applied automatically to reduce
the vehicle speed. (Brake control: See
figure 3 below.)
