Hyundai Mobis has developed reverse driving support technology that autonomously steers when a car goes in reverse, without the driver having to operate the steering wheel. Though there is already a parking assist system that autonomously steers a car in reverse parking, this is the first time that a technology has been specifically developed to support reverse driving.
The reverse driving support system autonomously steers a car when the car goes back to the location from which it came. The method stores the speed and travel paths when a car moves forward and automatically turns the car back by calculating the speed and travel paths in reverse.
The new technology is expected to alleviate the difficulties of reverse driving, which is particularly challenging for inexperienced drivers.
Contrary to the driving assistance system (DAS), which directly recognizes external environments through cameras, radars and ultrasonic sensors, Hyundai Mobis’s reverse drive support tech grasps external environments through real-time driving information. Under this method, a steering angle sensor, a wheel sensor and a yaw sensor installed inside a vehicle measure the car’s speed, distance and degree of rotation.
As the whole industry has focused on forward autonomous driving technology, expensive cameras, lidar and radar sensors are concentrated at the front of a car. As a result, the back of a car is supported only by a rear camera and ultrasonic sensors that measure short distances, and this makes it difficult to actively recognize external environments.
To solve this challenge, Hyundai Mobis came up with the creative idea of utilizing the existing sensors of a car, improving both versatility and price competitiveness. The company is now planning to develop a complete reverse driving technology that supports both starting and braking by adding more cameras and radar sensors.
