What does PEPS mean when displayed on a car?

PEPS on a car stands for Passive Entry Passive Start, which is a keyless one-button start system. It is also known as the keyless system. The smart key automatically unlocks the doors and deactivates the anti-theft system when you approach the vehicle within a certain distance, and it locks the doors and activates the anti-theft system when you leave. In simple terms, the PEPS keyless system in a car recognizes the authorized driver when they enter a specified range and automatically unlocks the doors. When leaving the car, the doors lock automatically and the anti-theft system is activated. Below is how the car PEPS system works: 1. Signal transmission: When the car key is carried near the vehicle and the car button is pressed or the door handle is pulled, the car receives a signal for ignition or unlocking and sends a signal to the low-frequency antenna. 2. Reverse signal transmission: Upon receiving the signal, the low-frequency antenna sends a low-frequency trigger signal to the car key. 3. Unlock signal: The car key receives the low-frequency trigger signal and sends a high-frequency unlock signal.

What are the causes of parking brake failure?

The causes of parking brake failure include malfunctioning parking brake and inability to fix the control lever. Below are detailed explanations regarding parking brake failure: Parking brake malfunction: The main reason for malfunction is excessive clearance between the friction lining and the brake drum, oil contamination on the friction lining and brake drum, severe wear of the friction lining, exposed rivets, surface hardening causing slippage, severe wear of the parking brake pin shaft, excessive clearance, or over-adjustment of the parking brake pull rod. Therefore, inspection and adjustment should be performed before driving. Inability to fix the control lever: When braking with the parking brake, after pulling the parking brake control lever to the braking position and releasing it, it cannot be fixed in the braking position. During inspection, first press and release the control lever head, then grip and release the control lever handle, performing up and down movement tests to check if the control lever is bent, stuck, or if the spring is broken. If no issues are found, check if severe wear of the sector gear and pin has caused slipping.

Will an Automatic Car Move Without Pressing the Accelerator?

When the gear of an automatic car is in P (Park) or N (Neutral), the car will not move whether the accelerator is pressed or not. However, when the gear is in any position other than P or N, the car will move when the accelerator is pressed and may also move without pressing the accelerator. It's important to note that automatic cars should not be put in neutral, as coasting in neutral can damage the automatic transmission. Below are some common misconceptions about using an automatic transmission: Keeping the car in D (Drive) for long periods while parked: If the brake pedal is pressed for an extended period, it forcibly stops the car from moving forward, causing the transmission fluid temperature to rise and the fluid to degrade, especially when the engine is idling higher with the air conditioning system running. High-speed driving: This can potentially burn out the transmission, as the transmission output shaft rotates at high speed while the engine idles, leading to insufficient oil supply from the transmission pump and worsening lubrication conditions.

What Causes Body Vibration When Accelerating Hard?

Reasons for body vibration when accelerating hard include damaged spark plugs, poor fuel quality, bent half-shafts, etc. Below are detailed explanations about body vibration during hard acceleration: Damaged spark plugs: Worn spark plug gaps result in insufficient ignition, causing incomplete combustion of the air-fuel mixture and vibration during acceleration. Cracks in the ceramic part of spark plugs may prevent ignition entirely. Poor fuel quality: Low-quality fuel leads to poor atomization by fuel injectors, resulting in incomplete combustion of the mixture in the cylinders. Bent half-shafts: Issues like bent vehicle half-shafts can cause rhythmic vibration in the front of the car.

How many times do you need to turn the steering wheel in an S-curve?

You need to turn the steering wheel twice in an S-curve. When driving on a curved path, it's essential to time your maneuvers correctly, maintain an appropriate speed, and use the clutch and brake to control the vehicle's speed. Before entering the curve, try to stay close to the right side of the path to avoid crossing the line. Below is an introduction to the S-curve driving test: Test requirements: The S-curve is a part of the second subject in the driver's test, commonly known as the S-bend. The test requires the vehicle to navigate through an S-shaped path of a specified width without touching the edge lines, demonstrating smooth and controlled steering. Assessment content: The test evaluates the driver's ability to maneuver the steering and control the vehicle on a curved path. The goal is to develop the driver's skill in using the steering and understanding the trajectory of the wheels.

What is the engine speed of the Hongqi H5 at 120 km/h?

Between 3000~3500 rpm. The engine speed is related to the number of power cycles per unit time or the effective power output of the engine, meaning the effective power varies with different speeds. Therefore, when specifying the effective power of an engine, the corresponding speed must also be indicated. The effective power and its corresponding speed specified on the engine's product nameplate are referred to as the rated power and rated speed, respectively. The operating condition of the engine at rated power and rated speed is called the rated condition. Rated power is not the maximum power the engine can produce; it is the maximum usable limit of effective power determined based on the engine's intended use. For the same engine model, the rated power value may differ depending on its application. Effective torque also varies with engine conditions. Therefore, the maximum torque output and its corresponding speed are used as indicators to evaluate the dynamic performance of automotive engines.
