TRANSPORT ONBOARD SECURITY CHECK
An example operation includes one or more of saving a hash of data including occupant data and transport data on a transport in response to the transport is started, performing a security check that validates the hash of data against the data in response to the transport is started, and providing a resolution when the security check fails.
History-based and location-based control of vehicle key-off loads
An electrical system in a vehicle has a battery is configured to supply electrical current when a driver ignition key is in a Key-Off state. A. A plurality of electrical loads are each configurable to receive the electrical current flowing from the battery during the Key-Off state depending upon predetermined Key-Off-Load (KOL) Modes. A vehicle locator determines a geographic location of the vehicle. A sleep-time database records daily Key-On and Key-Off events according to changes between the Key-On state and the Key-Off state, wherein each Key-Off event is associated with a respective geographic location from the vehicle locator. An analyzer identifies Key-Off events sharing a repetitive time span and a common geographic location. A scheduler activates a timed KOL sequence according to the identified Key-Off events so that repetitive time slots of vehicle usage can be used to reduce battery drain during times when vehicle usage is less likely.
Methods and apparatus for contactor weld detection in a vehicle
The proposed mechanism for weld detection, uses isolation monitoring circuits (which is used for measurement of the leakage current between battery positive and negative to the chassis ground (on pack or link side) and checks the health status of the contactors. The mechanism connects isolation monitoring circuit between two points on the battery pack (between two sides of the high current contactors) and measures the resistance of two points, therefore checking the continuity of the contactors in the system. Since it can measure a range of resistance, it can also check if a contactor is completely welded or it has been partially welded. This would be important because in case of partial weld, the car can fix the problem and remove the partial weld by activating and deactivating the contactors for several time, with or without inserting high current in the coil of the contactors. Since the proposed mechanism is using available measurement circuits of the isolation monitoring unit and these circuits are designed with high reliability (which is required for the electrical vehicles), the proposed mechanism is going to lower the cost of the entire vehicle while keeping the passenger safe.
VEHICLE MOUNTED ELECTRONIC CONTROL APPARATUS
The present invention has been made in view of the above problems, and an object of the present invention is to, when an abnormality is detected in an electronic control apparatus that controls a plurality of functions, continue an operation without affecting the other function and secure safety of a control target device corresponding to the function in which the abnormality is detected. In the vehicle mounted electronic control apparatus according to the present invention, each of a first computing portion and a second computing portion outputs an operation check signal, and a driver control unit sets a driver corresponding to the computing portion in which an abnormality is indicated by the operation check signal among the first computing portion and the second computing portion, to a degenerated state.
ABNORMALITY DIAGNOSIS SYSTEM
An abnormality diagnosis system configured to diagnose an abnormality of an electric drive system mounted on a mobile body to drive a motor for moving the mobile body, includes: an information acquisition unit configured to acquire a motor output information which is information related to an output state of the motor; an output state determination unit configured to determine whether the output state of the motor is in a low output state that does not contribute to a movement of the mobile body by using the motor output information; and a diagnosis execution unit configured to diagnose an abnormality of the electric drive system when it is determined that the motor is in the low output state.
External and internal power management for embedded electronic devices
A power management system is provided to manage internal and external power sources for an embedded electronic device. The power management system includes an internal power source and an external power source. The power management system determines when to power the internal embedded electronic device or devices from either the internal or external power source, when to recharge the internal power source, when to shut down the internal embedded electronic device so as not to over discharge and damage the internal power source when external power is not available.
SYSTEM AND METHOD IN DATA-DRIVEN VEHICLE DYNAMIC MODELING FOR PATH-PLANNING AND CONTROL
Operation and motion control, by a vehicle's ADAS or AD features, is improved in ways suitable to EVs having higher driving and handling performance. The vehicle dynamic model for high rates of lateral acceleration (e.g., sharp cornering or taking curves having a small radius of curvature as faster speeds) is improved by one or more of optimizing time cornering stiffness with a sigmoid function and/or altering front/rear steering angle to account for roll steer and compliance steer, based on vehicle testing. Indicators for lane departure warning or collision warning, evasive steering, or emergency braking are therefore reliably extended to allow higher performance maneuvers.
AUTOMATED CONTROL ARCHITECTURE THAT HANDLES BOTH GRIP DRIVING AND SLIDING
Systems and methods of autonomously controlling a vehicle across the grip driving and drift driving operating ranges, are provided. The contemplated autonomous control can be effectuated using a closed-loop control system. In some embodiments, closed-loop control may be accomplished by deriving control laws involving sideslip angle, yaw rate, wheel speed, and other vehicle states. These control laws may be used to control the vehicle in a stable drift condition.
Damper interface device
A damper interface device (DID) includes a microcontroller including a memory and a processor, at least one algorithm stored to the memory, and a DID connector configured to connect the microcontroller to a vehicle network without having to modify the wiring system of the vehicle. The algorithm is configured to receive network messages from the vehicle network via the DID connector, where the network messages include an input message directed to a suspension controller. The algorithm is executed by the processor to identify the input message as directed to the suspension controller, parse the input message for response requirements, determine contents of a response to the input message, where the contents of the response emulate a response of the suspension controller, and generate a response message including the contents of the response. The microcontroller is configured to output the response message to the vehicle network via the DID connector.
