Purpose, function

• An anti-intrusion brake pedal has been adopted to the brake pedal to provide for a measure of safety in the event of an accident.

• The anti-intrusion brake pedal suppresses the minimized amount of brake pedal retreat during a frontal collision, softening impact to the lower body of the driver.

Construction

• For the anti-intrusion brake pedal, the brake pedal structure consists of the following parts.

― Pedal arm

― Lever

― Pin A

― Pin B

― Pin C

― Bracket

Operation

During normal braking

• When the brake pedal is operated, the pedal arm rotates using pin A as a pivot, and the pedal force is transmitted to the electronically controlled brake unit fork.

• The pedal force presses the fork and the brake is applied.

During anti-intrusion operation

• If the dashboard panel moves towards the driver's seat during a frontal collision, the brake pedal also moves with it.

• As a result, the force in the X direction is applied to the brake pedal lever because the dashboard member interferes with the lever.

• The force is applied to the lever in the X direction, pin C is detached from the bracket, and the lever rotates using pin B as the pivot.

• When the lever rotates, it interferes with pin A which is the pivot of the pedal arm.

• When the lever further rotates, pin A is detached from the bracket (notch) and the pedal arm moves freely.

• Impact to the lower body of the driver is softened by the pedal arm being able to move freely.
