Provided are a vehicle driving information providing method and system, the method including: operating in a turning radius control mode by determining a parking situation or a U-turn situation while a vehicle is driving; determining a driving force for each of wheels located on left and right sides of the vehicle according to one predetermined configuration mode, which is set up for an operation in the turning radius control mode, among a plurality of predetermined configuration modes including different target turning radii of the vehicle; and generating and outputting an expected driving path of the vehicle, based on the determined driving force.

Vehicle driving information providing method and system

A control method for an SSC function and an ISG function includes: determining, by a controller, whether a SSC activation condition is satisfied based on a vehicle running state information; stopping, by the controller, an engine and activating the SSC function by controlling a transmission to neutral when the SSC activation condition is satisfied; determining, by the controller, whether a first ISG operation condition including a first reference vehicle speed is satisfied based on the vehicle running state information in a state that the SSC function is activated; and deactivating, by the controller, the SSC function and activating the ISG function when it is determined that the first ISG operation condition is satisfied.

Control method for SSC and ISG of vehicle and vehicle to which the control method is applied

A control method for a Start Stop Coasting (SSC) function and an Stop and Go (ISG) function of a manual transmission vehicle includes: determining, by a controller, whether an SSC activation condition is satisfied based on vehicle running state information; stopping, by the controller, an engine and disengaging a clutch to activate the SSC function when the controller determines that the SSC activation condition is satisfied; determining, by the controller, whether a first ISG operation is satisfied based on the vehicle running state information in the state that the SSC function is activated; and deactivating, by the controller, the SSC function and activating the ISG function when the controller determines that the first ISG operation condition is satisfied.

A system and method for preventing a failure of an exhaust heat recovery device are provided. The method includes operating a sole exhaust heat recovery mode when cooling water has a temperature less than a warm-up reference temperature to introduce all exhaust gas flowing from a DPF into the exhaust heat recovery device where the exhaust gas exchanges heat with the cooling water. Additionally, a passage through which the exhaust gas bypasses the exhaust heat recovery device is opened when the exhaust gas at a rear of the DPF has a temperature greater than the warm-up reference temperature during the sole exhaust heat recovery mode.

System and method for preventing failure of exhaust heat recovery device

A cooling system for a vehicle may include a cooling water temperature sensor, a cooling circulation fluid passage including first, second and third fluid passages, wherein the cooling water exhausted from the engine may be branched into the first fluid passage provided with a heater core, the second fluid passage provided with a radiator, and the third fluid passage provided with an exhaust heat recovery apparatus, a fluid flow adjusting valve provided on a point at which the cooling water passing through the cooling water temperature sensor may be branched into the first fluid passage to the third fluid passage to adjust a flow of the cooling water, and a controlling part controlling the first fluid passage to the third fluid passage to be selectively opened or closed by operating the fluid flow adjusting valve depending on the temperature of the cooling water, in a heating mode and a non-heating mode.

Cooling system for vehicle and controlling method thereof

A method for controlling a cooling system in a vehicle, may include an Exhaust Gas Recirculation (EGR) use determination step of determining whether to use EGR, a first coolant temperature management step of controlling a coolant temperature using a first coolant temperature map based on an output value reflecting engine operating conditions when driving the vehicle using the EGR, and a second coolant temperature management step of controlling the coolant temperature using a second coolant temperature map in which a coolant temperature of the second coolant temperature map may be set to be higher than a coolant temperature of the first coolant temperature map in a same engine operation region when driving the vehicle not using the EGR.

Method for controlling cooling system in vehicle

A mild hybrid system according embodiments of the invention may include: a motor-alternator; an inverter for controlling electrical energy flow to and from the motor-alternator; an electrical energy storage for storing electrical energy generated by the motor-alternator; and a unidirectional DC/DC buck converter including a bypass means for providing a physical connection between the motor-alternator and a vehicle electrical load. With the system, the manufacturing cost can be reduced, packaging process can be simplified, and an additional cooling device is not required.

Mild hybrid system and method for controlling the same

A charging system for a hybrid vehicle which prevents a super capacitor from being reverse charged. In the illustrative charging system a DC-DC converter is connected to the inverter and configured to receive the DC electricity from the inverter and drop voltage. A battery is configured to receive the DC electricity from the DC-DC converter and to be charged by the DC electricity. Finally, a means for preventing reverse charging is mounted on a path between the super capacitor and the battery and is configured to prevent energy from flowing from the battery to the super capacitor.
