A real time clock device for a vehicle may include: a register set provided with a first register, in which second time information is stored, and configured to store Real Time Clock (RTC) data including the time or date; and a data compensation circuit to block an input of a 1 second (1 s) tick to the first register and compensate for a delay time according to the block of the input of the 1 s tick to the first register by an RTC lock signal during a process of transmitting the RTC data to an external device or receiving setting data for the RTC data from the external device.

Real time clock device for vehicle and operating method thereof

An injector driver and an operating method thereof are provided in which a driving semiconductor directly controls a brake signal when a brake error occurs in driving an injector, to thus secure a safety function. The injector driver a driving semiconductor configured to transmit an interrupt signal for acknowledging whether a brake signal has been received to a micro-control unit (MCU) when a brake signal is applied. In addition, the driving semiconductor receives a brake signal recognition acknowledgement response signal from the MCU and detects whether the MCU has an error based on the brake signal recognition acknowledgement response signal reception result. Further, the driving semiconductor operates an injector driving signal when the response signal is not received from the MCU for a predetermined period of time.

Injector driver and operating method thereof

A device for correcting injector characteristics includes: an injector-characteristic detection unit that outputs a selection signal by detecting drive characteristics of injectors in response to a selection control signal; a selection control unit that outputs the selection control signal for selecting a factor for deviation correction to the injector-characteristic detection unit; a selection confirmation unit that confirms a variation value of the factor corresponding to the selection signal; a deviation correction unit that calculates a deviation compensation value corresponding to the injector characteristics in response to an output signal of the selection confirmation unit, and thus output a correction signal; a control unit that generates a correction clock in response to the correction signal; and an output drive unit that controls driving of the injectors in response to the correction clock.

Device for correcting injector characteristics

An injector driver and a method of controlling the injector driver are provided. A defect of a driving channel is detected by enabling an identification of safety inspection for each channel in a driving semiconductor during an idle mode. The injector driver includes a plurality of driving switches that operate an injector and a driving semiconductor that drives of the driving switches. In addition, the driving semiconductor determines a short defect of the injector during an idle mode and detects and stores the defective short in a channel unit.

Injector driver and method of controlling the same

A technique for correcting injector characteristics is provided. In particular, a micro control unit is configured to generate a control pulse for controlling the operation of an injector; and a driving semiconductor is configured to detect and calculate a driving characteristic of the injector and compensating for injection timing of the control pulse in accordance with a deviation in injection timing of the injector.

Technique for correcting injector characteristics in engine of vehicle

A serial communication test device, a system including the same, and a method thereof are provided, which relate to a technology that allows a master chip and a slave ship for Serial Peripheral Interface (SPI) communication to double-check data to increase reliability. The serial communication test device includes an interface that is configured to transmit and receive data to and from an external chip. A controller is configured to store data to be error-checked in a register to output the stored data to the external chip through the interface and to store data received from the external chip through the interface in a data storage unit. The controller compares the data stored in the register with the data stored in the data storage unit and determines whether the data stored in the register is substantially similar to data to be error-checked.

Serial communication test device, system including the same and method thereof

An apparatus and method for monitoring multiple micro-cores enable one watchdog to monitor a plurality of micro-cores. The multiple micro-core monitoring apparatus includes: a plurality of micro-cores that periodically output clear signals having different pulse waves; and a watchdog that respectively receives the clear signals having different pulse waves so as to determine presence or absence of an error in the micro-cores, and reset an erroneous micro-core.
