A vehicle ventilating/cooling system may include at least one sun-load sensor arranged within the vehicle, and a controller configured to receive a sun-load signal indicating a sun-load level from the sensor and programmed to instruct at least one cooling component to conduct a purge of vehicle cabin air in response to the sun-load level exceeding a sun-load threshold.

The invention relates to a method and a device for operating a drive train (101) of a hybrid vehicle comprising an electrical system (102), the drive train (101) having at least one vehicle drive wheel (105) in addition to one first electrical machine (104) and the first electrical machine (104) being connected to the electrical system (102). According to the invention, in order to stabilize the voltage of the electrical system (102), the first electrical machine (104) is operated without being coupled to the drive wheels (105) of the hybrid vehicle.

An electronic control unit diagnoses a short failure of an inverter FETs and diagnoses whether the failure of the FET-short detecting section has occurred. The unit controls a motor through an inverter including a bridge having an upper-stage FETs and a lower-stage FETs via an MCU, having: an FET-short detecting section to detect a short failure of the upper-stage FETs and the lower-stage FETs based on respective connection point voltages of the upper-stage FETs and the lower-stage FETs; and a diagnostic function to detect a failure of the FET-short detecting section. The diagnostic function diagnoses the failure of the FET-short detecting section at start up and turns-OFF the upper-stage FETs and the lower-stage FETs when the failure is detected. The FET-short detecting section diagnoses the short failure of the upper-stage FETs and the lower-stage FETs when the failure of the FET-short detecting section is not detected.

Systems of an electrical vehicle and the operations thereof are provided. In particular, a towing cable and methods for utilizing the same in a towing scenario are described. The towing cable is described to facilitate the transfer of power between vehicles as well as data between vehicles. The data transferred between the vehicles involved in the towing include sensor information of the towed vehicle as well as control signals.

A battery system includes an electricity storage device including a plurality of battery units. The electronic control device is configured to switch a travel mode of the vehicle between a CD mode and a CS mode. The electronic control device is configured to calculate a vehicle state of charge at a higher value than an average state of charge when the average state of charge is higher than a threshold value, and calculate the vehicle state of charge at a lower value than the average state of charge when the average state of charge is lower than the threshold value. The threshold value is set at a lower value than a center value between an upper limit value and a lower limit value of the vehicle state of charge.

A self-monitoring and self-controlling smart irrigation system is provided. The smart irrigation system may include a plurality of tower control units, which tower control units include one or more processors, one or more memory units, and communication circuitry. The tower control units may be configured to determine one or more operational conditions of the smart irrigation system, to communicate to other tower control units the operational conditions, and to make adjustments based on the operational conditions. The tower control units may be configured for expedient and efficient replacement and maintenance in that they may be readily detachable from the smart irrigation system.
