Toyota CH-R: Acoustic vehicle alerting system

When the gasoline engine is off while driving, a sound is produced to warn pedestrians, people riding bicycles or other people and vehicles in the surrounding area that the vehicle is approaching. The pitch of the sound adjusts according to vehicle speed. When vehicle speed is approximately 25 km/h (16 mph) or more, the warning system turns off.

■Acoustic vehicle alerting system

In the following cases, the acoustic vehicle alerting system sound may be difficult for pedestrians, people riding bicycles or other people and vehicles in the surrounding area to hear:

• When there is a lot of noise in the vicinity
• When it is raining or during strong winds
• When in the area surrounding the rear of the vehicle, rather than in front of the vehicle

Predictive efficient drive (if equipped)

This system operates based on the driving situation and traffic information to enhance fuel economy.

For details about Predictive efficient drive, refer to "Multimedia owner's manual".

■ Predictive deceleration support

• When the vehicle approaches to predictive deceleration support points registered in the navigation system, the reference operation range (A) of the ECO Accelerator Guidance on the multi-information display will be turned off to encourage the driver to reduce excessive acceleration.

With 7-inch display:

With 12.3-inch display:

• The engine braking force will be increased according to the driving conditions to more efficiently charge the hybrid battery (traction battery) after the accelerator pedal is released.

■ Predictive SOC* control

The following types of control are performed based on data such as road and traffic information during route guidance by the navigation system to help ensure that the vehicle efficiently uses electricity.

• When there is a long downhill slope along the route, the system reduces the hybrid battery (traction battery) level before reaching the slope to help ensure charging capacity for regenerative braking while traveling downhill.
• When traffic congestion is predicted along the route, the system helps ensure a certain battery level before reaching congested roads to reduce the frequency of starting the engine to charge the hybrid battery (traction battery) due to low battery levels.
