Problems solved by technology

However, an average or inexperienced driver of a vehicle equipped with a conventional yaw stability control system may behave erratically in complex situations, for example due to panic, and thus be unable to guide the yaw stability control system to maintain a safe trajectory

Embodiment Construction

[0035] In summary, the embodiments herein exploit knowledge about the road to address certain limitations of conventional yaw stability control systems that are not prepared to exploit what is foreseen to be more or less common in future vehicles. The road preview performance of the standard feature.

[0036] As in conventional yaw stability control systems, determinations by on-board systems and sensors such as inertial measurement units provide information about the state of the associated vehicle, for example information about the speed and yaw rate of the associated vehicle.

[0037] Additionally, the embodiments herein rely on the fact that data can be read from on-board systems such as sensor systems such as vision systems (cameras), LIDAR (light detection and ranging, also known as lidar) systems, RADAR (radio detection and ranging) system and / or obtain information about the road ahead, ie the future geometric path of the road, from a digital mapping system such as a GP...

Abstract

Embodiments herein relate to a vehicle yaw stability control method as well as a vehicle yaw stability control apparatus (1). The yaw rate È of the vehicle is measured. A first reference yaw rate È ref is set. A difference yaw rate ” È is set. Stabilizing braking intervention is triggered when a value of the difference yaw rate ” È exceeds limits defined by difference yaw rate threshold values ” È min , ” È max . Information regarding the shape of the road ahead of the vehicle is acquired. The reliability of the driver steering input ´ is evaluated upon stabilizing braking intervention being triggered. In case the driver steering input ´ is deemed unreliable a replacement reference yaw rate È Ù ref road is set based on the acquired road shape and a replacement difference yaw rate ” È road is set whereupon stabilizing braking intervention is performed based on the replacement difference yaw rate ” È road .

Description

technical field [0001] Embodiments herein relate to a vehicle yaw stability control method and a vehicle yaw stability control apparatus. Background technique [0002] According to recent studies, about half of all major accidents in motorized countries involve the loss of a single vehicle. Studies have also shown that unintentional route deviations are the leading cause of these traffic fatalities. [0003] The automotive industry has developed active safety systems aimed at avoiding or mitigating accidents. One example is a yaw stability control system that helps the driver regain control of the vehicle. Yaw stability control systems have proven effective in reducing the number of traffic accidents. [0004] Conventional yaw stability control systems are very dependent on the driver's actions when controlling the vehicle's motion. Based on the steering wheel angle provided by the driver, the yaw stability control system calculates a desired trajectory to follow when th...
