  • Publication number: 20230079933
    Abstract: Systems and methods for determining whether a vehicle is in an understeer or oversteer situation. The system includes a controller circuit coupled to an IMU and an EPS, and programmed to: calculate, for a steered first axle, an axle-based pneumatic trail for using IMU measurements and EPS signals and estimate a saturation level as a function of a distance between the axle-based pneumatic trail and zero. The system estimates, for an unsteered second axle, an axle lateral force curve with respect to a slip angle of the second axle, and a saturation level as a function of when the axle lateral force curve with respect to the slip angle transitions from positive values to negative values. The saturation level of the first axle and the second axle are integrated. The system determines that the vehicle is in an understeer or oversteer situation as a function of the integrated saturation levels.

  • Publication number: 20230077837
    Abstract: Collaborative perception is based on recognition that a fleet of AVs and stationary infrastructure objects equipped with sensors may be configured to communicate with one another in sharing their sensor data, thus benefiting from collaborative perception, rather than being limited to their individual perception. Three specific scenarios of collaborative perception are disclosed. The first scenario relates to two AVs in the vicinity of one another exchanging complexity scores indicative of their respective environments. The second scenario relates to an AV detecting that it has a blind spot and seeking other AVs or infrastructure objects to provide information indicative of the environment in the blind spot. The third scenario relates to providing infrastructure objects equipped with sensors in appropriate locations so that, when an AV is in the vicinity of such objects, the AV may receive information from their sensors.

  • Patent number: 11603925
    Abstract: Presented are clutch control systems for torque converter (TC) assemblies, methods for making/operating such TC assemblies, and vehicles equipped with such TC assemblies. A TC assembly includes a housing that drivingly connects to an electric motor, and an output member that drivingly connects to a multi-gear transmission. Rotatable within the TC housing are a turbine attached to the TC output member and an impeller juxtaposed with the turbine. A lockup clutch is operable to lock the housing to the output member. A system controller is programmed to receive a shift signal to shift the powertrain from a neutral or park operating mode to a forward driving operating mode; responsive to receipt of this shift signal, the lockup clutch is opened. The system controller then receives a TCC lock signal to lock the lockup clutch; responsive to receipt of the TCC lock signal, the lockup clutch is closed.
