PKSB-What Is A Parking Support Brake?

Are you familiar with the PKSB Parking Support Brake

The PKSB Parking Support Brake system includes the following functions, which are activated while driving at a low speed or backing up, such as when parking. When the system concludes that there is a high likelihood of a collision with a detected object, a warning is sent to advise the driver to take evasive action. If the system decides that the likelihood of a collision with a detected object is very high, the brakes are immediately deployed to assist prevent or mitigate the effect of the accident.

PKSB (Parking Support Brake) system

■ Parking Support Brake function (static objects) Ultrasonic sensors are used to detect static objects, such as a wall, in the detection area when driving at a low speed or backing up.

■ Parking Support Brake function (rear-crossing vehicles) (if equipped) Rear radar sensors are used to detect approaching vehicles in the detection area behind the vehicle when backing up.

■ Parking Support Brake function (rear pedestrians) (if equipped) A rear camera sensor is used to detect pedestrians in the detection area behind the vehicle when backing up.

NOTICE

■If “Parking Support Brake Unavailable” is displayed on the multi-information display and the PKSB OFF indicator is flashing If this message is displayed immediately after the power switch is changed to ON mode, operate the vehicle carefully, paying attention to your surroundings. It may be necessary to drive the vehicle for a certain amount of time before the system returns to normal. (If the system is not return to normal after driving for a while, clean the rear camera lens.)

 

WARNING

Cautions regarding the use of the system

  • Do not overly rely on the system, as doing so may lead to an accident.
  • Always drive while checking the safety of the surroundings of the vehicle.
  • Depending on the vehicle and road conditions, weather, etc., the system may not operate.
  • The detection capabilities of sensors and radars are limited. Always drive while checking the safety of the surroundings of the vehicle.
  • The driver is solely responsible for safe driving. Always drive carefully, taking care to observe your surroundings. The Parking Support Brake system is designed to provide support to lessen the severity of collisions. However, it may not operate in some situations.
  • The Parking Support Brake system is not designed to stop the vehicle completely. Additionally, even if the system has stopped the vehicle, it is necessary to depress the brake pedal immediately as brake control will be canceled after approximately 2 seconds.
  • It is extremely dangerous to check the system operations by intentionally driving the vehicle into the direction of a wall, etc. Never attempt such actions.

When to disable the Parking Support Brake

In the following situations, disable the Parking Support Brake as the system may operate even though there is no possibility of a collision.

  • When inspecting the vehicle using a chassis roller, chassis dynamo or free roller
  • When loading the vehicle onto a boat, truck or other transport vessel
  • If the suspension has been modified or tires of a size other than specified are installed
  • If the front of the vehicle is raised or lowered due to the carried load
  • When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
  • When using automatic car washing devices
  • If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or is malfunctioning
  • When the vehicle is driven in a sporty manner or off-road
  • When the tires are not properly inflated
  • When the tires are very worn
  • When a tire chains, compact spare tire or an emergency tire puncture repair kit is used.

Notice:

  • If “PKSB Unavailable” is displayed on the multi-information display and the PKSB OFF indicator is flashing
  • If this message is displayed immediately after the power switch is changed to ON, operate the vehicle carefully, paying attention to your surroundings. It may be necessary to drive the vehicle for a certain amount of time before the system returns to normal. (If the system is not return to normal after driving for a while, clean the sensors and their surrounding area on the bumpers.

FAQS

What does the brake assist system do?

Brake assist is an advanced safety system that is become increasingly more common amongst models including family vehicles in the new car market. Essentially, brake assist systems help reduce the stopping distance when emergency braking takes place in a car.

How does the brake assist system work?

How Does Emergency Brake Assist Work? When the vehicle detects that the brake pedal is being used to achieve a sudden stop, the emergency brake assist pushes the pedal all the way to the floor. Keep your foot on the brake in order for your anti-lock brakes to engage if it is needed.

Is brake assist the same as ABS?

ABS rapidly pumps the brakes during a hard stop to prevent your vehicle from skidding and sliding. Without it, the brakes can lock up and send a car careening dangerously out of control [source: Consumer Reports]. Brake assist simply allows the ABS system to stop the car even more effectively.

How do you check brake assist?

Turn the engine off, then repeatedly press the brake pedal slowly. When you pump it the first time the pedal should be very ‘low’— meaning not much pressure resistance. As you pump the pedal, the pressure should become firmer, which will indicate that the brake booster is not leaking.

What are the two types of brake assist systems?

There are two types of brake assist systems. The classic type is the mechanical brake assist and the newer type is the electronic brake assist. The thing that separates the two brake assist systems is how they detect emergency braking when you step on the brake pedal.

Does brake assist really work?

Numerous studies show that brake assist is the real deal, with the potential to prevent thousands of fatal auto accidents each year. In this article, we’ll take a look at what allows brake assist to stop cars much more quickly and effectively than the unaided driver can do alone.

What does service brake assist mean?

What Does The Term “Service Brake Assist” Imply? Brake assist is a car safety function that assists drivers in coming to a faster stop during an emergency braking situation. Brake assist is a feature that recognizes the signals of emergency braking and provides more brake support to drivers.

How does Toyota Brake Assist work?

Toyota’s Brake Assist system measures the speed and force with which the brake pedal is pushed to estimate whether the driver is attempting to brake rapidly or not, and applies additional braking pressure to maximize braking performance for both conventional and anti-lock brake system (ABS) equipped vehicles.
