Embodiment Construction

[0016] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0017] A system that automatically adjusts the operating mode of a vehicle controller may be referred to as a vehicle adaptive drive control (ADC) system. In an example, the vehicle may utilize the suspension settings ADC to automatically select between a sport suspension mode, a normal suspension mode, and a comfort suspension mode to adjust to meet road-grade roughness conditions an...

Abstract

The present disclosure relates to low traction detection and mode selection for adaptive driving controls. A controller may indicate a low traction mode of the vehicle when longitudinal tracking accumulation exceeds a first threshold and lateral response accumulation exceeds a second threshold. The longitudinal track accumulation may measure traction control system activation counts over time. The lateral response accumulation may measure vehicle yaw rate compared to a model predicted yaw rate angular velocity based on driver expectations. The controller may indicate the low traction mode by providing a recommendation to switch to the low traction mode in a human machine interface screen of the vehicle or by automatically adjusting the operating mode of at least one electronic control unit of the vehicle to implement the low traction mode.

Description

technical field [0001] Aspects of the present disclosure generally relate to road surface condition detection and mode selection for adaptive driving control. Background technique [0002] Various vehicle subsystems are known to operate in different configuration modes to accommodate different conditions, which vary over time. For example, the automatic transmission can be controlled in Sport, Winter, Economy, and Manual configurations, in which changes between gear ratios and other subsystem control parameters are modified to suit current conditions or the driver's preferences preference. Electric active suspension systems and adaptive suspension systems are known to have on-road and off-road configuration modes. The power steering system can be operated in different configuration modes with varying levels of assistance. [0003] Traditionally, the operation of each vehicle subsystem has been manually controlled by the driver based on preference and experience. As the n...
