Problems solved by technology

[0002] However, when activated, ESA systems typically require the steering effort provided by the system to drop before providing the additional steering effort needed to avoid objects
Not only does this drop cause a delay in providing additional steering effort, but it can be unsettling to the vehicle driver (for example, they may feel as if the power steering has failed)

[0060] Although various embodiments of an ESA with a pre-activation phase have been described in language specific to particular features and / or methods, the subject matter of the appended claims is not necessarily limited to the particular features or methods described. Rather, certain features and methods are disclosed as example implementations of an ESA with a pre-activation phase. Further, while various examples have been described above, each having particular features, it should be understood that a particular feature of one example need not be used only with that example. Instead, any of the features described above and / or depicted in the drawings may be combined with any of the examples in addition to or instead of any of the other features of the examples. combination.

Abstract

Techniques and systems are described that implement evasive steering assist (ESA) with a pre-activation phase. The ESA system predicts an impending collision with the object and enters a pre-activation phase. The pre-activation phase results in a required drop in steering force prior to determining that a collision is imminent. At a later time, the ESA system determines that a collision is impending and performs an activation phase. The activation stage generates a steering force that effectively avoids collision. By performing a pre-activation phase prior to determining an impending collision, the ESA system may provide the additional steering force required to avoid the collision without delay, while leaving the driver of the vehicle unable to feel a decrease in steering force.

Description

Background technique [0001] Driver assistance technologies are increasingly being implemented in vehicles to improve safety. Evasive Steering Assist (ESA) is a driver assistance technology that enables a vehicle to automatically steer to avoid a collision with an object. For example, a vehicle may determine that a collision with an object is imminent and provide steering force to the vehicle to avoid the object. [0002] However, when activated, ESA systems typically require the steering effort provided by the system to drop before providing the additional steering effort needed to avoid objects. Not only does this drop cause a delay in providing additional steering effort, but it may be unnerving to the vehicle driver (eg, they may feel as if the power steering has failed). Contents of the invention [0003] Aspects described below include a method of evasive steering assistance (ESA) performed by a vehicle. The method includes determining at least one of a state of the ...
