This system helps reduce occupant injuries in rear-end collisions.

Rear end collision is the most frequent type of traffic accidents.

Rear end collision is most frequent and accounts for approximately 30% of total accidents in Japan.
The laser radar sensor detects the distance to a preceding vehicle and the relative velocity. If necessary, the system activates the brakes of the vehicle.

The vehicle assists the driver's braking action according to the situation. Intelligent Brake Assist helps avoid rear-end collisions, and it also works in concert with the Brake-Operated Pre-crash Seatbelts to help mitigate injuries in the event a collision is unavoidable.

Intelligent Brake Assist

When there is a risk of a collision with the vehicle in front and the driver must take avoidance action immediately.

iba_02.gifThe system sounds a warning to prompt action by the driver to help avoid a rear-end collision.

When a rear-end collision cannot be avoided by the driver's action.

iba_03.gifThe system activates the brakes to decelerate the vehicle, thereby helping to reduce occupant injuries resulting from the collision.

When the system judges emergency braking is needed, based on the distance to the followed vehicle and relative velocity.
