Parking Support Brake function (rear-crossing vehicles)

If a rear radar sensor detects a vehicle approaching from the right or left at the rear of the vehicle and the system determines that the possibility of a collision is high, this function will perform brake control to reduce the likelihood of an impact with the approaching vehicle.

Examples of function operation

This function will operate in situations such as the following if a vehicle is detected in the traveling direction of the vehicle.

■ When reversing, a vehicle is approaching and the brake pedal is not depressed, or is depressed late

■The Parking Support Brake function (rear-crossing vehicles) will operate when

The function will operate when the PKSB OFF indicator is not illuminated or flashing and all of the following conditions are met:

• Engine output restriction control
  • The Parking Support Brake is enabled.
  • The vehicle speed is approximately 15 km/h or less.
  • Vehicles are approaching from the right or left at the rear of the vehicle at a traveling speed of approximately 8 km/h or more.
  • The shift lever is in R.
  • The Parking Support Brake determines that a stronger than normal brake operation is necessary to avoid a collision with an approaching vehicle.
• Brake control
  • Engine output restriction control is operating
  • The Parking Support Brake determines that an emergency brake operation is necessary to avoid a collision with an approaching vehicle.

■The Parking Support Brake function (rear-crossing vehicles) will stop operating when

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

• Engine output restriction control
  • The Parking Support Brake is disabled.
  • The collision becomes avoidable with normal brake operation.
  • A vehicle is no longer approaching from the right or left at the rear of the 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.
  • A vehicle is no longer approaching from the right or left at the rear of the vehicle.

■Detection area of the Parking Support Brake function (rear-crossing vehicles)

The detection area of the Parking Support Brake function (rear-crossing vehicles) differs from the detection area of the RCTA function. Therefore, even if the RCTA function detects a vehicle and provides an alert, the Parking Support Brake function (rear-crossing vehicles) may not start operating.
