Toyota Prius: Parking Support Brake function (rear pedestrians)

If the rear camera sensor of the Toyota Prius detects a pedestrian behind the vehicle while backing up and determines there is a high possibility of a collision, it activates a series of safety measures. Initially, a buzzer will sound to alert the driver to the potential danger. This auditory warning aims to prompt the driver to take immediate action to avoid the collision. However, if the system assesses that the risk of colliding with the detected pedestrian is extremely high and the driver does not respond in time, the brakes will be applied automatically. This automatic braking feature is designed to reduce the speed of the vehicle and, consequently, the impact of the collision, enhancing pedestrian safety and minimizing potential injuries. The integration of this advanced safety technology underscores Toyota's commitment to protecting both drivers and pedestrians with proactive and responsive safety systems.

Examples of system operation

The system operates when an approaching pedestrian is detected behind the vehicle while backing up, and when the brake pedal is not depressed or is depressed late.

Correct use of the Parking Support Brake function (rear pedestrians)

Parking Support Brake function (rear pedestrians) will operate when

The function will operate when the driving assist information indicator is not illuminated  and all of the following conditions are met:

• Hybrid system output restriction control

• The Parking Support Brake is enabled.
• The vehicle speed is 9 mph (15 km/h) or less.
• The shift position is in R.
• A pedestrian is to the rear of the vehicle
• The PKSB (Parking Support Brake) determines that a strongerthan- normal brake operation is necessary to avoid a collision.

• Brake control

• Hybrid system output restriction control is operating.
• The Parking Support Brake determines that an emergency brake operation is necessary to avoid a collision with a pedestrian.

The Parking Support Brake function (rear pedestrians) will stop operating when

The function will stop operating if any of the following conditions are met:

• Hybrid system output restriction control

• The Parking Support Brake is disabled.
• The collision becomes avoidable with normal brake operation.
• The pedestrian is no longer detected behind your vehicle.

• Brake control

• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed since the vehicle was stopped by brake control.
• The brake pedal is depressed after the vehicle is stopped by brake control.

Detection area of the Parking Support Brake function (rear pedestrians)

The detection area of the Parking Support Brake function (rear pedestrians) differs from the detection area of the RCD function .

Therefore, even if the RCD function detects a pedestrian and provides an alert, the Parking Support Brake function (rear pedestrians) may not start operating.
