    摘要: Temperature compensation for ultrasonic sensors can have a significant error that is highly undesirable because temperature of ultrasonic sensors and the temperature of the medium through which they sense objects affect signal strength calibrations (e.g., echo thresholds) applied when detecting an object. In order to increase the detection capabilities and reported distance of an object, ultrasonic sensors need to adjust their detection criteria and distance calculations as the temperature of air surrounding a vehicle (i.e., outside air temperature) changes and also as the temperature of the sensor changes. Embodiments of the inventive subject matter provide for a simple, effective and consistent approach for determining a temperature upon which such detection criteria and distance calculation adjustments can be based.

    摘要: An automotive vehicle braking system and method for controlling the same. The system includes an electronic controller communicatively coupled to a vehicle braking system and a vehicle motion detection device. The braking system is configured to be automatically activated in response to detection of an object in a path of the vehicle. Once activated, the braking system is deactivated either by the driver or a pre-determined time period after detection that motion of the vehicle has stopped. Prior to deactivation of the vehicle braking system an HMI message is activated indicating imminent deactivation of the vehicle braking system.
