Vehicle electronic control apparatus

A first monitoring control circuit unit monitors controlling operation of an engine control unit (ECU); when the occurrence frequency of an abnormality becomes the same as or larger than a predetermined threshold value, a first storage circuit stores that occurrence frequency and a first cutoff circuit de-energizes an intake valve opening degree control motor for an air-intake throttle so as to set the intake valve opening degree to a fixed intake valve opening degree; a second monitoring control means monitors controlling operation of a transmission control unit (TCU); when the occurrence frequency of an abnormality becomes the same as or larger than a predetermined threshold value, a second storage circuit stores that occurrence frequency and a second cutoff circuit de-energizes a gear-shifting electromagnet valve so as to set the transmission ratio to a fixed transmission ratio.

STARTING CONTROL DEVICE FOR ELECTRICALLY DRIVEN VEHICLE

A starting control device is provided for an electrically driven vehicle having an electric motor and an internal combustion engine as drive sources and a transmission shifts and transmits an output of the electric motor to a drive wheel. The starting control device is configured to suppress an abrupt increase in the rotation of the electric motor at the time of an EV start of the vehicle from a released state of a starting dog clutch. In the electrically driven vehicle, an EV start is carried out by transmitting the output of the first motor/generator (MG1) to the drive wheel via a starting dog clutch that is meshingly engaged. The output of the first motor/generator is limited until the starting dog clutch comes into a meshed state in which the transmission transmits drive power at the time of start from a released state of the starting dog clutch.

Control system for hybrid vehicle

A control system for hybrid vehicle for extending a possible travelling distance of the vehicle in the event of clutch failure is provided. The control system is configured to select a first drive mode in which the vehicle is powered by an engine in case an estimated torque transmitting capacity of the clutch in trouble is larger than a first threshold value, and to select a second drive mode in which the vehicle is powered by a motor in case the estimated torque transmitting capacity of the clutch in trouble is smaller than the first threshold value. The control system is further configured to reduce an engine torque to be smaller than the estimated torque transmitting capacity of the clutch in case the first drive mode is selected.

METHOD FOR CONTROLLING HYDRAULIC PRESSURE REFILLING OPERATION FOR ENGINE CLUTCH OF HYBRID ELECTRIC VEHICLE

A method for controlling a hydraulic pressure refilling operation for an engine clutch of a vehicle includes determining whether the vehicle travels using power of a driving motor with an engine clutch maintained in a disengaged state, and upon determining that the vehicle travels using power of the driving motor with the engine clutch maintained in the disengaged state, determining whether loss of hydraulic pressure has occurred, and upon determining that loss of hydraulic pressure has occurred, controlling a hydraulic pressure refilling operation such that working fluid in a reservoir is supplied to the actuator with the engine clutch in an engaged state, and controlling the driving motor so that the driving motor outputs a compensated torque by compensating for an effect of a load torque, generated by a non-operating engine, on a torque of the driving motor.

Self-driving vehicle sensor fault remediation

Methods, systems, and computer program products for self-driving vehicle sensor fault remediation are provided herein. A computer-implemented method includes detecting a fault in one or more sensors of a self-driving vehicle; determining a remedial action in response to the detected fault, wherein said determining comprises (i) comparing the fault to a database comprising (a) historical sensor fault information and (b) sensor fault remedy information, and (ii) analyzing one or more items of contextual information pertaining to the location of the self-driving vehicle; generating a signal comprising one or more instructions pertaining to carrying out the determined remedial action; and outputting the generated signal to one or more remote-controlled pilotless airborne devices configured to remotely carry out the determined remedial action on the self-driving vehicle.

Method for controlling a vehicle assembled from a set of modules, a control device, a vehicle, a computer program and a computer-readable medium

A method for controlling a vehicle (1) assembled from a set of modules (20). The vehicle (1) includes: at least one drive module (30); and at least one functional module (40). The at least one drive module (30) has a pair of wheels (32) and is configured to autonomously operate and drive the assembled vehicle (1) wherein the modules (30, 40, 70, 80) of the vehicle (1) are configured to communicate with the control device (100). The method includes: receiving (s101) data from the modules (30, 40, 70, 80) of the vehicle (1), wherein the data includes a value of at least one parameter associated with a current condition of the modules (30, 40, 70, 80); evaluating (s102) the received data by comparing the value of the at least one parameter with a predetermined value or value interval for the at least one parameter; and controlling (s103) the vehicle (1) based on the evaluation.

Systems and methods for managing battery state of charge

An inverter power module: selectively applies power from a battery to a permanent magnet (PM) electric motor; and selectively provides power output by the PM electric motor for the battery. A switch, when open, prevents power flow the inverter power module from the battery, and, when closed, enables power flow between the inverter power module and the battery. An adjustment module determines an SOC adjustment based on at least one of a vehicle speed and a temperature of the battery. A maximum module receives a first maximum SOC of the battery and that determines a second maximum SOC of the battery based on the first maximum SOC and the SOC adjustment. A clutch control module disengages a clutch, decoupling the PM electric motor from a transmission, when the switch is stuck closed and an SOC of the battery is greater than the second maximum SOC.

AUTONOMOUS VEHICLE DIAGNOSTIC SYSTEM

An on-board diagnostic system for an autonomous vehicle can receive diagnostic data from any number of AV systems of the AV. For each AV system the on-board diagnostic system can determine whether the diagnostic data indicates that the AV system is operating nominally. In response to determining a fault condition of an AV system, the on-board diagnostic system can initiate a procedure associated with the respective AV system to resolve the fault condition.
