Collision avoidance by braking is appropriate at low vehicle speeds (e.g. below 50 km/h (31 mph)), while collision avoidance by steering may be more appropriate at higher vehicle speeds if lanes are clear. [10] Cars with collision avoidance may also be equipped with adaptive cruise control, using the same forward-looking sensors.
Collision avoidance by braking is appropriate at low vehicle speeds (e.g. below 50 km/h (31 mph)), while collision avoidance by steering may be more appropriate at higher vehicle speeds if lanes are clear.

Adaptive cruise control does not provide full autonomy: the system only provides some help to the driver, but does not drive the car by itself. [3] For example, the driver is able to set the cruise control to 55mph, if the car while traveling that speed catches up to another vehicle going only 45mph, the ACC will cause the car to automatically brake and maintain a safe distance behind the ...
[3] [8] It features a wheelbase of 106.3 inches (2,700 mm), 1.1 inches (28 mm) longer than the 1993 Jeep Grand Cherokee, 5.1 inches (130 mm) longer than its predecessor, the Jeep Cherokee XJ, and 2.7 inches (69 mm) shorter than the original Jeep Cherokee (SJ). The Jeep Cherokee could be equipped with three different four-wheel-drive systems ...
Collision avoidance system (pre-crash system) uses small radar detectors, typically placed near the front of the car, to determine the car's vicinity to nearby obstacles and notify the driver of potential car crash situations. [34] These systems can account for any sudden changes to the car's environment that may cause a collision. [34]
Some systems also feature forward collision warning systems, which warn the driver if a vehicle in front—given the speed of both vehicles—gets too close within the preset headway or braking distance. Vehicles with adaptive cruise control are considered a Level 1 autonomous car, as defined by SAE International. [22]
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
Electronic stability control (also known as roll over protection) is a specific technology that helps keep the vehicle balanced. During harsh weather or tough road conditions that would cause vehicle steering to be extreme, this technology allows the drivers to regain control and prevent possible crashes, roll overs, and fishtails.
