A coolant system includes a battery coolant line fluidly connected to a battery, a power electronics coolant line fluidly connected to a power electronic component, a radiator coolant line fluidly connected to a radiator, a control valve configured to allow the battery coolant line, the power electronics coolant line, and the radiator coolant line to be fluidly connected to or separated from each other, a temperature sensor disposed in at least one of the battery coolant line, the power electronics coolant line, or the radiator coolant line, and a controller configured to control a switching operation of the control valve under a predetermined condition in a manner that fluidly connects a coolant line without any temperature sensor to a coolant line with the temperature sensor, and determine a temperature of a coolant passing through the coolant line without any temperature sensor based on a temperature sensed by the temperature sensor.

Vehicular coolant system and method of controlling the same

A method for controlling an electric heater of a vehicular heating, ventilation, and air conditioning (HVAC) system includes turning on the electric heater; determining whether an ambient air temperature of a vehicle is higher than or equal to a threshold ambient air temperature, and a battery temperature is lower than or equal to a threshold battery temperature; determining whether battery efficiency is lower than or equal to threshold efficiency when the ambient air temperature of the vehicle is higher than or equal to the threshold ambient air temperature, and the battery temperature is lower than or equal to the threshold battery temperature; and turning off the electric heater when the battery efficiency is lower than or equal to the threshold efficiency, wherein the electric heater is configured to receive electric energy from the battery.

Method for controlling electric heater of vehicular HVAC system

Vehicle control apparatus and vehicle control method are described. The vehicle control apparatus may include a compressor and a controller. The controller may determine a thermal load level at one or more of: a first time point at which an engine is switched to an ON state from an OFF state, a second time point at which a first discharge amount of the battery exceeds a first reference value while the engine is in the OFF state, or a third time point at which a second discharge amount of the battery exceeds a second reference value smaller than the first reference value and a discharge rate associated with the battery exceeds a third reference value while the engine is in the OFF state. The controller may control the compressor using a control value corresponding to the thermal load level.

Vehicle control apparatus and vehicle control method

A front end module for a vehicle includes a first box-type mounting part and a second box-type mounting part. The first box-type mounting part is disposed on a connection portion of a front end module lower member with a front side member. The second box-type mounting part is disposed on a front end portion of the front side member. The first and second box-type mounting parts are coupled to each other by bolt coupling or welding such that sections thereof are connected to each other upon assembling of the front end module and the front side member.

Front end module for vehicle

A bumper-stay structure for a vehicle, provided between a bumper back beam and a side member, for absorbing collision impact, may include a buffer member fixed to a front end of the side member and having a first impact absorbing member slidably absorbing the collision impact while the collision impact is applied to the bumper back beam, a support member, a front end of which is coupled to the bumper back beam and a rear end of which is telescopically mounted to a front end of the buffer member, wherein the rear end of the support member is pressingly coupled by the first impact absorbing member to the buffer member so that the first impact absorbing member maintains pressing contact with the support member while the collision impact is applied to the bumper back beam.
