Abstract: A system for vehicle pitch control during braking includes a pitch component and a rebound component. The pitch component is configured to determine that a vehicle has a forward pitch during braking. The rebound component is configured to, in response to the vehicle achieving a substantially zero forward velocity, apply brake pressure to one or more non-driven wheels using one or more brakes and apply reverse torque to one or more driven wheels using a motor or engine.

Abstract: Wireless transmission of wheel rotation direction is disclosed. A disclosed apparatus includes a tone ring exhibiting a rotational asymmetry and a detector to measure a rotational direction of a wheel of a vehicle based on the rotational asymmetry and to measure a rotational speed of the wheel, where the detector or the tone ring is operatively coupled to the wheel. The disclosed apparatus also includes a wireless transmitter to transmit the rotational direction and the rotational speed to a receiver proximate or within an engine compartment of the vehicle.

Abstract: An autonomous pulse and glide system and method are disclosed. Pulse and glide is a fuel savings strategy that pulses a host vehicle to a maximum target speed and glides to a minimum target speed. Where the host vehicle detects that a lead vehicle is within a minimum distance the pulse and glide strategy is modified. The system may interrupt a pulse or may instruct the host vehicle to pass the lead vehicle. The host vehicle may also include an inter-vehicle communication module which facilitates a master/slave interaction with a lead or trailing vehicle.

Abstract: An apparatus for placing a fuel cell stack in a standby mode is provided. The apparatus comprises a compressor, a fuel cell stack, a cathode valve and a controller. The compressor is operably coupled to an air induction system for providing a cathode stream. The fuel cell stack provides electrical power to a load in response to the cathode stream. The cathode valve is operably coupled to an outlet of the fuel cell stack for controlling a flow of the cathode stream to the fuel cell stack. The controller is configured to receive a power request amount for the load and to compare the power request amount to a predetermined amount. The controller is further configured to control the compressor to operate at a minimum speed and the cathode valve to close in response to determining that the power request amount is similar to the predetermined amount.

Abstract: A fuel cell system includes a fuel cell stack for generating power, a compressor providing an air stream to the stack, and a controller. The controller is configured to, in response to determining a mass air flow through the compressor from a lookup table using a speed of the compressor and a pressure ratio across the compressor, operate the fuel cell system based on the mass air flow. A method for controlling a fuel cell system includes receiving first and second signals at a controller indicative of air pressure upstream and downstream of a compressor respectively, and receiving a third signal at the controller indicative of a speed of the compressor. The fuel cell system is operated at a desired mass air flow based on an inferred mass air flow determined using the first, second, and third signals.

Abstract: A method is presented for idle speed control of a lean burn spark ignition internal combustion engine using a fuel-based control strategy. In particular, the idle speed control strategy involves using a combination of fuel quantity or timing and ignition timing to achieve desired engine speed or torque while maintaining the air/fuel ratio more lean than prior art systems. Depending on engine operating conditions, the fuel quantity or timing is adjusted to give a more rich air/fuel ratio in order to respond to an engine speed or torque demand increase. Additionally, due to operation close to the lean misfire limit, the spark ignition timing is adjusted away from MBT in response to an engine speed or torque demand decrease. The advantages of this fuel based control system include better fuel economy as well as fast engine response time due to the use of fuel quantity or timing and ignition timing to control engine output.
