| 发明名称 | Static road gradient estimation | ||
| 摘要 | A vehicle and a vehicle system are provided with a controller that is configured to generate output indicative of a static road gradient estimation based on a filtered longitudinal acceleration. The filtered longitudinal acceleration is dependent upon a derivative of a longitudinal acceleration. An initial value of the static road gradient estimation corresponds to at least one of a kinematic road gradient estimation and a dynamic road gradient estimation. | ||

| 主权项 | 1. A vehicle comprising: an engine configured for automatic shutdown and restart; a controller configured to filter a longitudinal acceleration using a low pass filter having a bandwidth selected from a plurality of bandwidths based on a derivative of the longitudinal acceleration,generate output indicative of a static road gradient estimation based on the filtered longitudinal acceleration,wherein the controller is further configured to shutdown and restart the engine based on the static road gradient estimation; wherein an initial value of the static road gradient estimation corresponds to at least one of a kinematic road gradient estimation and a dynamic road gradient estimation. | ||
