2018 Toyota C-HR with many ADAS features

The C-HR is equipped with standard Toyota Safety Sense P (TSS-P). It has standard Pre-Collision System with Active Braking as well as Full-Speed Range Dynamic Radar Cruise Control as standard equipment.

TSS-P is a multi-feature advanced active safety suite that bundles Pre-Collision System with Pedestrian Detection function (PCS w/PD) featuring forward collision warning and Automatic Emergency Braking; Lane Departure Alert with Steering Assist function (LDA w/SA); Automatic High Beams (AHB); and Full-Speed Range Dynamic Radar Cruise Control (DRCC).

The Pre-Collision System with Pedestrian Detection (PCS w/PD) uses a camera and radar to detect a vehicle and/or pedestrian ahead of the C-HR in certain conditions. When the system determines there is a possibility of collision, it prompts the driver to brake with an audio and visual alert. If the driver notices the hazard and brakes, the system may provide additional braking force using Brake Assist. If the driver fails to brake in a set time and the system determines that the risk of collision with a vehicle and/or pedestrian is extremely high, the system may automatically apply the brakes, reducing speed in order to help the driver avoid the collision or reducing the impact.

Lane Departure Alert (LDA) with Steering Assist function uses an in-vehicle camera designed to detect visible white and yellow lane markers in front of the vehicle and the vehicle’s position on the road. If the system determines that the vehicle is starting to unintentionally deviate from its lane, the system alerts the driver with an audio and visual alert. When the alerts occur, the driver must check the surrounding road situation and carefully operate the steering wheel to move the vehicle back to the center part of their lane.

In addition to the alert function of LDA, the C-HR will feature a Steering Assist function. If the system determines that the vehicle is on a path to unintentionally depart from its lane, the system may provide small corrective steering inputs to the steering wheel for a short period of time to help the driver keep the vehicle in its lane.

On highways, Full-Speed Range Dynamic Radar Cruise Control (DRCC) functions similar to conventional “constant speed” cruise control in that it helps vehicles travel at a consistent speed set by the driver, but this system adds a vehicle-to-vehicle distance control mode designed to assist the driver by adjusting vehicle speed to help maintain a pre-set distance to a preceding vehicle when the preceding vehicle is traveling at a lower speed. Once a vehicle speed is set by the driver, Full-Speed Range DRCC uses a front-grill mounted millimeter-wave radar and an in-vehicle camera designed to detect a preceding vehicle and help determine its distance.

If the vehicle ahead is detected traveling at a speed slower than your set speed or within your distance range setting, the system is designed to automatically decelerate the vehicle without having to cancel the cruise control. When a greater reduction in vehicle speed is necessary, the system may apply the brakes and operate the vehicle brake lights. The system will then respond to changes in the speed of the vehicle ahead in order to help maintain the vehicle-to-vehicle distance set by the driver. When there is no longer a preceding vehicle driving slower than the vehicle’s set speed, the system accelerates until the set speed is reached and returns to the pre-set speed cruising. Full-Speed Range DRCC is designed to function at approximately 0 to 110 mph, and may enable low speed following, speed matching, stopping, and acceleration/deceleration to a preceding vehicle.

Automatic High Beams (AHB) helps enhance forward visibility during nighttime driving. It uses a camera to detect the headlights of oncoming vehicles and the tail lights of vehicles ahead, and then automatically switches between high beams and low beams so as not to interfere with other drivers.

Complementing TSS-P are 10 standard airbags, standard Hill-Start Assist Control (HAC) and rear backup camera, as well as available Blind Spot Monitor with Rear Cross Traffic Alert, which are only available on the XLE Premium model.
