Key Facts
- PKSB stands for 'Pre-Collision System with Brake,' an active safety feature offered on Toyota vehicles
- It uses millimeter-wave radar and monocular camera sensors to detect obstacles and other vehicles
- The system can automatically apply brakes when an imminent collision is detected
- PKSB is available on many Toyota models including Camry, Corolla, RAV4, Highlander, and Sienna
- It is part of the Toyota Safety Sense package, which includes additional driver assistance features
Overview
PKSB is Toyota's pre-collision safety system designed to detect potential front-end collisions before they occur and take preventive action. The system continuously monitors the road ahead using advanced sensors to identify obstacles, other vehicles, and pedestrians. When the system detects an imminent collision, it alerts the driver and, if necessary, automatically applies the brakes to help prevent the accident or reduce the severity of impact.
How It Works
The system operates through a combination of millimeter-wave radar and monocular camera technology. The radar identifies other vehicles and larger obstacles ahead, while the camera provides additional detection capabilities and can identify pedestrians. The system's computer processes this sensor data in real-time, calculating the likelihood of collision based on the vehicle's speed, distance to obstacles, and relative motion. When a collision risk is detected, the system first issues an audio and visual alert to the driver.
Automatic Braking
If the driver does not respond to the initial warning or if the collision risk increases, PKSB automatically applies the brakes. This automatic braking can range from mild brake application intended to supplement driver braking to full emergency braking in critical situations. The automatic braking intervention is designed to work in conjunction with driver inputs, providing additional protection if the driver is unable to brake in time.
Coverage and Limitations
PKSB is most effective in front-end collision scenarios, particularly with other vehicles on the road. The system's effectiveness can be reduced by adverse weather conditions such as heavy rain or snow, and it may not detect smaller obstacles or objects on the road. Additionally, the system is designed to assist drivers rather than replace attentive driving and proper vehicle control.
Availability and Integration
Toyota offers PKSB on a wide range of vehicle models as part of the Toyota Safety Sense suite. Different vehicle models may have variations in the specific features and capabilities offered. PKSB is generally available on higher trim levels of vehicles, though some newer models include it as standard equipment across the lineup.

What is Toyota Safety Sense?
Toyota Safety Sense is a comprehensive suite of advanced driver-assistance systems including PKSB, adaptive cruise control, lane departure alert, and lane keeping assist. It's designed to help prevent accidents and protect occupants through multiple interconnected safety technologies.
How do collision avoidance systems work?
Collision avoidance systems use sensors like radar and cameras to detect obstacles and potential collisions. They analyze this data to predict collision risks and take preventive action, typically through alerts and automatic braking.
What other safety features does Toyota offer?
Toyota vehicles include features such as blind spot monitoring, rear cross-traffic alert, lane keeping assist, adaptive cruise control, and automatic emergency braking as part of their comprehensive safety offerings.
