Adaptive door sealing using power cinching latch
The invention controls a power cinching function of a motor vehicle door latch in order to improve door seal performance under conditions wherein vibrations could otherwise reduce seal effectiveness. With the door latched closed in a flush condition, the vehicle speed is compared to a slow-speed threshold. When the vehicle speed is greater than the slow-speed threshold, then a vehicle vibration parameter is compared to a vibration threshold. When the vibration parameter is greater than the vibration threshold, then the power cinching function is activated to move the door to to a subflush condition which increases a compression of the seal between the door and a vehicle door frame. When the door is in the subflush condition, the vehicle speed continues to be compared to the slow-speed threshold, and when the vehicle speed is less than the slow-speed threshold then the door is released back to the flush condition.
Evaporator freeze prevention systems and methods
An air conditioning system of a vehicle having an internal combustion engine includes a condenser configured to receive refrigerant output by an electric compressor and transfer heat from the refrigerant within the condenser to air passing the condenser. A first evaporator is configured to receive refrigerant from the condenser when a first control valve is open and transfer heat from air passing the first evaporator to the refrigerant within the first evaporator. A first blower is configured to blow air across the first evaporator to a first section of a cabin of the vehicle. A second evaporator is configured to receive refrigerant from the condenser when a second control valve is open and transfer heat from air passing the second evaporator to the refrigerant within the second evaporator. A second blower is configured to blow air across the second evaporator to a second section of the cabin of the vehicle.
COOLING SYSTEM AIR FLOW DIAGNOSIS
A method of identifying air flow faults within a cooling system of an automobile comprises measuring the temperature of coolant entering a heat exchanger for the cooling system, measuring the temperature of coolant leaving the heat exchanger, and measuring the temperature of ambient air that is flowing into the heat exchanger, calculating Actual Delta T by subtracting the temperature of coolant leaving the heat exchanger from the temperature of coolant entering the heat exchanger, calculating Expected Delta T, wherein Expected Delta T is a pre-determined value of an expected difference between the temperature of the coolant entering the heat exchanger and the temperature of the coolant leaving the heat exchanger, calculating Effective Delta T by subtracting Expected Delta T from Actual Delta T, and identifying a fault in the air flow through the heat exchanger based on the value of Effective Delta T.
Apparatus and method for measuring interior temperature of vehicle
An apparatus and a method for measuring interior temperature of a vehicle, the apparatus includes a base substrate provided inside an interior panel of the vehicle and a housing including an infrared ray blocking material for inhibiting temperature of an inner space from being increased. The housing includes an exposed part provided in one side of the housing and exposed to an interior space of the vehicle, and an opening on a side portion of the exposed part for allowing the inner space of the housing to communicate with the interior space through the opening. The apparatus further includes a non-contact sensor provided on the inner space of the housing for measuring temperatures of the exposed part and the opening, and a controller calculating temperature of the interior space of the vehicle with the measured values by the non-contact sensor.
AUTONOMOUS VEHICLE CLIMATE OPTIMIZATION
A method for optimizing climate control in an autonomous vehicle. The method includes receiving a ride request for an autonomous vehicle from a customer. A desired temperature for an interior of the autonomous vehicle may be determined based on the ride request. The current temperature of the vehicle interior may then be adjusted such that the current temperature substantially matches the desired temperature when the autonomous vehicle reaches the customer. The temperature of the vehicle interior may be allowed to deviate from the desired temperature, within a pre-determined temperature deviation range, when the autonomous vehicle is unoccupied. A corresponding system and computer program product are also disclosed and claimed herein.
Air conditioner for vehicle
A vehicle air conditioner includes a bypass passage configured to cause a coolant to circulate while bypassing a heater core, a switching device set to switch between a first mode in which the coolant flows through the bypass passage and returns to an internal combustion engine while bypassing the heater core and a second mode in which the coolant flows to the heater core, a coolant-temperature sensor that detects a temperature of the coolant at a part through which the coolant flows in both the first mode and the second mode, and a control unit that controls an operation of a blower based on the coolant-temperature control data. Furthermore, first and second calculating portions are configured to calculate the coolant-temperature control data in the first and second modes, respectively. The first calculating portion calculates the coolant-temperature control data based on the temperature of the coolant detected at start-up of the internal combustion engine, and the second calculating portion sets, as the coolant-temperature control data, a temperature lower than the detected temperature of the coolant.

Temperature sensor for a vehicle
A temperature sensor for a vehicle that is designed to detect an interior temperature of the vehicle and that can be arranged in the vehicle. The temperature sensor provides improved usability and can be manufactured more easily. In particular, the temperature sensor allows raw data of the temperature sensor to be evaluated by the temperature sensor itself. An advantage of this setup thus is that a tedious sensor-specific adaptation of an associated control device in the vehicle for evaluating the raw data is not necessary. Different temperature sensors can be used with the control device without the control device having to be adapted in a different way to each of these temperature sensors.
