Evasive Steering Assist can assist the driver to avoid a collision with a slower or stopped vehicle ahead by providing steering support when the collision cannot be avoided by braking alone.
There are several ESA systems on the market, all having slightly different characteristics and unique proprietary names. For example, Ford and Mercedes have named their systems Evasive Steering Assist, while Volvo refers to its technology as Steering Support under the brand’s City Safety banner.
Names aside, the basic premise of each system is the same: To help maneuver around a slow-moving or stationary object when the driver cannot avoid it simply by braking.
The system has two main components – a multipurpose camera and a front radar sensor. The latest generations of multipurpose cameras combine AI methods and image processing algorithms. The advanced cameras now detect objects far ahead and assist in automated driving.
Once the vehicle circumvents the road hazard, the system helps the driver return to the intended course. It is important to note that the driver is ultimately in control of the steering; an ESA system does not take over the steering function. Instead, it assists the driver by giving additional support when needed.
The system never forces the driver’s hands from the steering wheel, and the driver can easily override the ESA system by retaking control of the steering wheel. Depending on the system, ESA operates at city and highway speeds.
The Global automotive Evasive Steering Assist market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
BOSCH automotive Evasive Steering Assist – The evasive steering support function supports the driver during a critical evasive maneuver by means of a supporting steering torque. This helps the driver in circumnavigating an obstacle to avoid an accident.
The evasive steering support function becomes active when the system detects an impending collision and the driver initiates the evasive maneuver.
Once the driver begins steering, the system intervenes in the power steering with torque in order to guide the vehicle around the obstacle.
From the video camera and radar sensor data the function instantaneously computes a suitable path, taking into account distance, width and offset of the preceding vehicle.
