摘要： The present invention provides a method for controlling an induction motor. The method comprises determining an input impedance of the motor at an operating point; determining an input electrical power to the motor at the operating point; and estimating a slip or shaft speed of the motor at the operating point from the input impedance and input electrical power.

摘要： System and method for vehicle drive cycle determination and energy management is provided. Based on a number of inputs, the system can determine the type of road that the vehicle is likely to drive on as well as the level of traffic congestion that the vehicle is likely to experience. Using these determinations, setpoints for various degrees of freedom, such as engine speed and battery power, can be set to reduce energy usage in the vehicle.

摘要： A pre-crash assessment system (1) includes a host vehicle (3) in motion and a high frequency sensor (4), which detects position and relative velocity of a target object in the near zone of the host vehicle (3). A safety device actuator (5) is also coupled to the host vehicle (3). A pre-crash algorithm provides a comparison of a future position prediction of the target object relative to the host vehicle (3). A safety device controller (9) is coupled to the host vehicle (3). The controller (9) generates a threshold assessment based on the target object future relative position and relative velocity. The controller (9) also controls the safety device actuator (5) by providing an actuation signal. The controller (9) operates through logic designed to estimate whether a potential for crash between the host vehicle (3) and the target object is within the threshold for the safety device actuator (5). The controller (9) activates the safety device actuator 5 when the potential for crash is within the pre-determined threshold and safety device specific deployment criteria are met.

摘要： A pre-crash assessment system 1 includes a host vehicle 3 in motion. A remote sensor 4, status monitoring sensors 5, and safety device actuators are coupled to the host object. The remote sensor 4 detects target object dynamics. The status monitoring sensors 5 detect host object dynamics. The safety device actuators activate safety devices. A threshold for each safety device actuator is defined by a safety device activation specification. A safety device controller 10, also coupled to the host object, generates tracking signals based on host object and target object dynamics. The safety device controller 10 also estimates future positions of the host and target objects, and estimates whether the potential for crash between the host and target objects is within the threshold criteria for specific safety device actuation. The controller 10 then controls the safety device actuators when the potential for crash is within the pre-determined threshold criteria.
