Toyota Launches New Hydrogen-fueled Car Sora

- Nov 26, 2019-

Recently, Toyota Motor Corporation announced that it will launch the latest "Sora" fuel cell electric vehicle bus in August and improve its preventive safety performance.

Specifically, Toyota improved preventive safety performance by using ITS (Intelligent Transportation System) functions. In addition, Sora's transportation capacity, speed and punctuality have been improved.

As a form of public transportation, Sora requires high operating speed and high safety performance at all times.

To this end, the updated model includes a function to remind the driver when turning right at the intersection, and a system that enables passengers to activate emergency parking in an emergency, such as when the driver suddenly becomes ill.

The updated Sora is equipped with a new system that can share information on the distance between vehicles to prevent two or more buses traveling in the convoy from being separated at the traffic lights and bus stops, enabling bus transportation Comprehensive improvement in ability, speed and punctuality.

The improvements made in this update are as follows:

Preventive safety features

Vehicles can be connected to the infrastructure's communication system and can share information about oncoming vehicles, pedestrians and traffic lights.

1. Turn right collision warning

When turning right at an intersection, the system will issue an alert to alert the driver of possible dangers, such as an oncoming vehicle or a pedestrian on the road.

2. Red light warning

When approaching the red light at the crossroads, the system will issue an alarm if the driver does not release the throttle or does not see the red light.

3. Red light deceleration assist

The system encourages early deceleration when approaching a crossroads and a red light may be encountered.

4. Signal change information

Emergency stop system

In the event of an emergency, such as a sudden illness of the driver, the system allows the driver or passenger to press the emergency brake switch to slow down and stop the car.

The control system is designed for public transportation buses where the safety of standing passengers is of paramount importance.

When the bus starts to decelerate, the red light flashes and there are voices to alert passengers that there is an emergency; people outside and near the vehicle use horns, flashing parking lights and danger lights to alert.

▲ Collision warning system

If a "millimeter wave radar" installed in the front of the bus detects the danger of a collision of a vehicle or an obstacle ahead, it will alert the driver with an alarm buzzer and activate an alarm notification on the monitoring screen.

The system takes into account the safety of standing and seated passengers who are not fastened with seat belts, and assists drivers to avoid collisions by assisting in driving.

Transportation capacity

Connected Vehicle-Fleet Information Service. The service uses bus information, bus order information, and distance information between buses traveling in the fleet to prevent the fleet from being isolated at traffic lights and bus stops, which helps improve transportation capacity, speed, and punctuality.

Fleet identification function

The system uses vehicle-to-vehicle communication and millimeter-wave radar to identify the information on the bus, the order of the bus, and the distance between the fleets within the maximum number of bus trips on any given road segment, and notify the driver of the size of the fleet.

In order to ensure that the entire fleet can pass a group of traffic lights at the same time, the last bus in the fleet sends a request to the traffic lights, requiring the traffic lights to remain green for a long time.

Vehicle-to-vehicle communication and millimeter-wave radar are used to identify the formation of convoys.

Bus start and stop information system

The system can identify when passengers get on and off the fleet and help ensure that the entire fleet leaves the station at the same time.

Communication radar cruise control

The bus is equipped with full-speed radar cruise control to support smooth acceleration and deceleration. If the previous car is also equipped with communication radar cruise control, the bus will use the information shared by the car-to-car communication to respond quickly to the acceleration and deceleration of the previous car, enabling the bus to follow smoothly.

The system also helps to maintain a constant inter-vehicle distance when escorting vehicles on a dedicated bus road, and helps to stabilize the speed of subsequent vehicles.

Speed and punctuality

The system uses a dedicated radio to send requests to infrastructure equipment to extend the green light time or reduce the red light time.

As the team moved, the last car in the team issued a request to extend the green time, thereby reducing the risk of the team being separated by a red light.


The system detects the guide lines on the road and automatically turns and decelerates to make the bus stop at the designated pick-up and drop-off positions, and minimize the distance to the bus station itself. This helps passengers get in and out of the stroller or wheelchair.发送反馈历史记录
