Driving Control Device
There is no consideration on performing charging control on a battery necessary for limp-home travel according to a travel environment of a vehicle. It is assumed that the vehicle changes a travel lane to a second travel lane by overtaking or the like between time t1 and t0. The second power generation threshold generation unit 33 refers to the lookup table 50 illustrated in FIG. 5 and reads 70 as the second charging threshold SOCth2. Then, the second charging threshold SOCth2 is larger than the first charging threshold SOCth1 as illustrated in FIG. 6(C), and thus, the threshold selection unit 34 outputs the second charging threshold SOCth2 as the selected charging threshold SOCth. At this time, the SOC of the battery is lower than the charging threshold SOCth, and thus, the power generation command value GEN is turned on at time t1, and the power generation engine is started to charge the battery. As a result, when the vehicle is traveling on the second travel lane which is far from an evacuation road 407, a large amount of energy is required for a limp-home operation for returning to the evacuation road 407, and thus, the battery can be sufficiently charged.
HYBRID PROPULSION SYSTEM POWER MANAGEMENT
An example method of managing power in a hybrid propulsion system includes receiving, by one or more processors, a power demand that specifies an amount of power to be used to propel a vehicle that includes an electrical energy storage system (ESS) and one or more electrical generators, wherein the one or more electrical generators are configured to convert mechanical energy to electrical energy; determining, based on the power demand and a predetermined ESS output limit, a first amount of power to be sourced from the ESS and a second amount of power to be sourced from the one or more generators; and causing, by the one or more processors, the ESS to output the first amount of power onto a direct current (DC) electrical distribution bus and the one or more generators to output the second amount of power onto the DC electrical distribution bus.
Hybrid vehicle and method for controlling the same
A hybrid vehicle may include an engine controller that determines an activation state of an oxygen sensor when the engine controller is requested to operate an engine and controls a voltage applied to the oxygen sensor depending on whether or not the oxygen sensor is in an activated state, and a vehicle controller that controls a voltage of a battery of the hybrid vehicle and applies the voltage of the battery to the engine controller. The engine controller outputs an activation demand signal for the oxygen sensor to be activated to the vehicle controller when it is determined that the oxygen sensor is not in the activated state.
ELECTRIFICATION CONTROL SYSTEMS AND METHODS FOR ELECTRIC VEHICLES
A system is provided for performing an automated electrification operation for an electric vehicle (102) using a processor (122). An electrification controller (126) communicates with a model generation unit (128). The model generation unit (128) generates a model representative of a power consumption trend of the electric vehicle (102). The electrification controller (126) sets a target power margin for the electric vehicle (102) based on the model such that the target power margin is close to a minimum state-of-charge (SOC) threshold of an energy storage supply (124) of the electric vehicle (102). The target power margin represents a difference between the minimum SOC threshold and an ending power level of the energy storage supply (124) after completion of a mission associated with the electric vehicle (102). The processor (122) performs the automated electrification operation for the electric vehicle (102) based on the target power margin.
Systems and methods for supplying power in a hybrid vehicle using capacitors, a battery and one or more DC/DC converters
A system for discharging or charging a capacitor of a hybrid vehicle according to the present disclosure includes a target state of charge (SOC) module and a capacitor charge/discharge module. The target SOC module determines a target state of charge of the capacitor based on a speed of the vehicle. The capacitor charge/discharge module determines whether a state of charge of a capacitor is greater than a target state of charge. The capacitor charge/discharge module dissipates power from the capacitor to at least one of a battery of the vehicle and an electrical load of the vehicle when the state of charge of the capacitor is greater than the target state of charge.

Methods and systems are provided for controlling an engine idle-stop based on upcoming traffic and road conditions. In one example, a method may include receiving data including traffic information and road characteristics immediately ahead of a vehicle from one or more remote sources, and adjusting one or more vehicle thresholds based on the received data. A duration of a prospective engine idle-stop may be estimated based on the received data and an engine idle-stop may be initiated based on the duration of the prospective engine idle-stop and the adjusted one or more vehicle threshold.
