摘要:
The present invention provides a regenerative system and method for determining the occurrence of a braking imbalance between at least two wheels. In the event of a braking imbalance a vehicle controller generates signals that cause a reduction in the regenerative braking force and a corresponding increase in friction braking force being applied to the vehicle wheels.

A combination secondary master cylinder and brake pedal compliance device for an automotive braking system includes a cylinder having a signal chamber, a working chamber, and a compliance chamber. Elastic devices mounted within the working chamber and compliance chamber allow the apparent compliance of the friction braking system attached to the combination device to remain at a relatively constant value notwithstanding the presence of varying amounts of powertrain braking.
摘要:
A control system for controlling a safety system of an automotive vehicle having a transmission and a differential. The system includes left and right wheel speed sensors associated with respective vehicle wheels and generating left and right wheel speed signals, and a transmission output shaft speed sensor generating a transmission output shaft speed signal. A controller is coupled to the wheel speed sensors and the transmission output speed sensor, and determines a reference wheel speed for one of the left or right wheels as a function of the other of the left or right wheel speed signal and the transmission output shaft speed signal. The controller controls the safety system in response to the determined reference wheel speed.

A method is provided for assuring that only the correct version of a software update is permitted to be installed in a computer controlled module, such as a vehicle controller. Each version of the software is embedded with a unique identifier, and each software update has an embedded list of the identifiers of the software versions which it is authorized to update or replace. A flashloader is used to determine if the identifier of the software in the controller is present in the list embedded in a proposed update, and installs the update if a match is found. Checksums and encryption of the identifiers can be used to enhance reprogramming integrity.
摘要:
A thin protective sheet for covering a face plate on an air mask. This thin sheet can come in many forms. For example, in a first embodiment, the sheet comprises a substantially rectangular thin sheet of plastic having a first edge with two substantially circular cut outs, and a second oppositely spaced edge having two substantially square cut outs and a substantially semi-circular cut out. In addition, there are positioned normal to these two sheets, two parallel spaced substantially flat edges. In the second embodiment of the invention, the sheet is a substantially rectangular thin sheet of plastic having an edge having a series of curves. There is also a second oppositely spaced flat edge and two oppositely spaced substantially flat edges positioned normal to the first edge and the second edge. The third embodiment is oval shaped and is designed to fit around a mask as well.

A vehicle headliner attachment system for mounting a headliner to a non-magnetic roof structure includes a headliner with an interior and an exterior surface, a magnet affixed to the exterior surface of the headliner, and a ferromagnetic clip mounted to the non-magnetic roof structure. The magnet and the ferromagnetic clip enable magnetic attachment of the headliner to the non-magnetic roof structure.
摘要:
An audio device incorporates a first acoustic driver having a first direction of maximum acoustic radiation and a second acoustic driver having a second direction of maximum acoustic radiation, where the first and second directions of maximum acoustic radiation are not in parallel, and where the audio device employs the first acoustic driver or the second acoustic driver in acoustically outputting a sound of a predetermined range of frequencies in response to the orientation of the casing of the audio device relative to the direction of the force of gravity.
摘要:
An apparatus include a first electronic component having first interface circuitry configured to generate an electromagnetic signal. The first electronic component is switchable such that in a first mode of operation, the first interface circuitry is configured to transmit the generated electromagnetic signal via a first antenna, and in a second mode of operation, the first interface circuitry is configured to transmit the electromagnetic signal to a second electronic component via a constrained signal path coupling the first electronic component and the second electronic component. The generated electromagnetic signal may be a radio frequency signal or an optical signal.

摘要:
An audio device incorporates a plurality of acoustic drivers and employs them to form either a first acoustic interference array generating destructive interference in a first direction from the plurality of acoustic drivers or a second acoustic interference array generating destructive interference in a second direction from the plurality of acoustic drivers in response to the orientation of the casing of the audio device relative to the direction of the force of gravity.
