Abstract:
A method of automated vehicle braking control includes detecting a first object threat in a reverse travel path of a vehicle, monitoring a distance of the vehicle from the first object threat with respect to a time to collision threshold, and in response to a determination that the vehicle is crossing the time to collision threshold, initiating a first rear virtual bumper event by automatically applying brakes of the vehicle. The method includes storing a location of the first object threat, defining a boundary region surrounding the location of the first object threat, detecting a second object threat in the reverse travel path, comparing a location of the second object threat with the boundary region, and inhibiting automatic application of the brakes in response to a determination that the location of the second object threat is within the boundary region, to avoid a second rear virtual bumper event.
Abstract:
A vehicle control system for evasive steering maneuvers includes a forward object detector configured to detect objects in a driving path of a vehicle, a steering wheel configured to control a steering direction of the vehicle, a vehicle user interface configured to display a visual indication to a driver and generate audio for the driver, and a vehicle control module configured to identify, via the forward object detector, an object in the driving path of the vehicle, determine an estimated time to collision with the object, and in response to the estimated time to collision being less than a specified time threshold, execute at least one of providing a visual indication of a recommended evasive steering maneuver to the driver via the vehicle user interface, generating an audio alert of the recommended evasive steering maneuver, applying steering torque to the steering wheel to indicate the recommended evasive steering maneuver.
Abstract:
A system according to the principles of the present disclosure includes a current object position module, an expected position module, and an object position comparison module. The current object position module can determine a first position of an object with respect to a position of a vehicle based upon sensor data generated by a first object detection sensor within the vehicle and determines a second position of the object with respect to the position of the vehicle based upon sensor data generated by a second object detection sensor. The expected object position module can determine an expected position of the object with respect to the position of the vehicle based upon the first position of the object. The object position comparison module can determine whether at least one object detection sensor is improperly installed within the vehicle based upon comparing the second position of the object with the expected position.
Abstract:
A control system for a vehicle using a forward-facing camera includes a look ahead module configured to determine a distance to a look ahead point. A lane center module determines a location of a lane center line. A vehicle center line module determines a location of a vehicle center line. A first lateral offset module determines a first lateral offset based on the look ahead point and the determined lane center line. A second lateral offset module determines a second lateral offset based on the determined lane center line and the vehicle center line. A yaw angle offset calculating module receives the first lateral offset, the second lateral offset and the distance to the look ahead point, calculates a yaw angle offset, and compensates a yaw angle error based on the yaw angle offset.
Abstract:
A system for a vehicle operating on a road includes a vehicle placement module that references, based on a geographic position of the vehicle, a road mapping database to identify a selected lane of the road where the vehicle is located. A lane assignment module (i) receives information indicating identification of an object in the road and (ii) determines a relative lane of the object with respect to the selected lane. A curvature plotting module determines a curvature line of the selected lane. An object placement module (i) determines a first distance value representing a shortest distance between the object and the curvature line and (ii) determines whether the relative lane of the object is the selected lane based on the first distance value and a lane width value. An alert generation module selectively generates an alert signal in response to the object being in the selected lane.
Abstract:
A system according to the present disclosure includes a lane boundary module, a vehicle trajectory module, an intersection location module, a lane departure module, and a driver warning module. The lane boundary module is configured to determine a boundary of a lane within which a vehicle is travelling. The vehicle trajectory module is configured to predict a trajectory of the vehicle. The intersection location module is configured to determine M locations of M intersections between the vehicle trajectory and the lane boundary at M times, where M is an integer greater than one. The lane departure module is configured to identify a potential lane departure based on the M locations. The driver warning module is configured to activate a driver warning device to warn a driver when the potential lane departure is identified.
Abstract:
A system including a current module, a second module, and a temperature module. The current module is configured to determine an amount of current drawn from a power source by a hydraulic pump of a transmission based on a current signal received from a current sensor. The current signal is indicative of the current drawn by the hydraulic pump. The second module is configured to determine (i) a speed of the hydraulic pump based on a speed signal received from a speed sensor, or (ii) an output torque of the hydraulic pump based on the amount of current drawn by the hydraulic pump. The speed signal is indicative of the speed of the hydraulic pump. The temperature module is configured to estimate a temperature of a hydraulic fluid circulated by the hydraulic pump based on (i) the amount of current drawn by the hydraulic pump, and (ii) the speed or the output torque of the hydraulic pump. The second module is configured to adjust the speed of the hydraulic pump based on the temperature of the hydraulic fluid.
