摘要:
A system and method for sensing vehicle global pitch angle and rate that uses global velocities measured from a single antenna global positioning system (GPS) receiver together with sensor fusion algorithms involving sensor signals and other computed signals. This constructed, or computed, vehicle body's pitch angle may replace the role of a pitch rate sensor in an integrated stability control system. Namely, it achieves enhanced vehicle state estimation without the need for a pitch rate sensor.

A cruise control system of a vehicle comprises a target generator, a speed controller, and a distance controller. The speed controller and the distance controller are each coupled to the target generator. The target generator is configured for generating a dynamic speed target and a dynamic distance target through real-time assessment of information characterizing current operating condition characterizing information. The speed controller is configured for utilizing the dynamic speed target for issuing commands to cause the vehicle to be operated at a road speed that is adaptive to the current operating condition characterizing information. The distance controller is configured for utilizing the dynamic distance target for issuing commands to cause the vehicle to be operated such that a distance between the vehicle and a leading vehicle is adaptive to the current operating condition characterizing information.

A system includes a vehicle computing processor. The processor is configured to, through wireless communication with a phone, and after determining that a vehicle engine is not running, request and receive motion sensor data from the phone. The processor is further configured to determine if a phone is moving with a driver based on the motion sensor data. Also, the processor is configured to alert the driver if the phone is not moving with the driver.
摘要:
A system and method for providing driving support system to a vehicle. The vehicle includes a set of control modules, having at least one operational setting, configured for electronically controlling the vehicle components. The system includes an integrated drive mode selection module having a set of drive modes for modifying the settings for each control module. A sensing system detects at least one condition associated with the driver, vehicle or surroundings. A controller determines an appropriate drive mode for the vehicle based on the condition and the output of a safety module that ensures that the drive mode is safe while driving.

A system for alerting a responsible party to the presence of an occupant in a passenger compartment of a vehicle includes a vibration sensor detecting movement of an occupant, a microphone detecting sound made by the occupant, a processor configured to receive signals output from the vibration sensor and the microphone and to use a combination of the signals to determine whether the occupant is present, and an alerting device to provide an alert to the responsible party if the processor determines that the occupant is present. The microphone may also be used in a communication or voice-recognition command system. Two or more microphones may be used to locate the sound's source of origin.
摘要:
A vehicle may include a driver interface and at least once controller operatively arranged with the interface. The at least one controller may be configured to categorize a driver's dynamic control of the vehicle by type, determine a target speed of a road curvature, and determine a speed of the vehicle. The at least one controller may be further configured to determine a threshold distance based on the type, determine a distance between the vehicle and the curvature, and generate an alert for the driver if the distance is less than the threshold and the speed is greater than the target.

A method for advising a driver of a vehicle including a haptic driver interface may include determining a speed of the vehicle, determining a distance between the vehicle and another vehicle, and activating the haptic driver interface based on the speed and distance.

A method for robust occupant position control prior to vehicle impact is provided. The method includes, in response to detecting an object, generating a Collision Index (CI) value representing a likelihood of collision with the detected object, and generating a Lateral Displacement (LD) value indicative of a distance to the detected object. A weight value (Wo) for a vehicle occupant is also determined. When the CI and LD values exceed respective thresholds, the method generates a pretensioner output (PTout) value as a function of the CI and Wo values, and activates a seatbelt pretensioner associated with a seat of the vehicle occupant as a function of the PTout value. An occupant positioning system for a vehicle activated prior to vehicle impact is also provided.
摘要:
A method for tuning a vehicle's performance may include measuring a plurality of parameters representing the vehicle's current handling condition and the vehicle's limit handling condition, determining a margin between the vehicle's current handling condition and limit handling condition, characterizing the driver's dynamic control of the vehicle based on the margin, and altering at least one tunable vehicle performance parameter based on the characterization.
